== Musical Instrument (Percussion) ==

The PorchBoard Floor Bass is a simple [http://en.wikipedia.org/wiki/Percussion_instrument percussion instrument] designed to be tapped by a foot to provide a "kick drum"-like sound.  It could be classed as an instrument of [http://en.wikipedia.org/wiki/Percussion_instrument#Indefinite_pitch indefinite pitch] containing complex frequencies through which no discernible pitch can be heard.<ref>Wikipedia [http://en.wikipedia.org/wiki/Percussion_instrument#Indefinite_pitch Wikipedia/Percussion Instrument#indefinite pitch]</ref>
  
Here are some learnings about playing this instrument through the {{L1}}.
+
With very little audible sound by itself, the internal pickup provides both 1/4" and XLR output connections that may be used simultaneously.  
  
* You get a different sound based on where along the tap-rail you place your foot (as well as how hard, of course). This worked well for emphasizing different beats, with softer taps being near the outside end of the rail and the louder ones nearer the middle.
+
* The [http://porchboard.com/RP.html RP PorchBoard] was introduced in January 2010. It replaces all previous models including all the features of all previous models in a smaller package.

== Settings on the {{L1}} for the PorchBoard ==
 +
=== {{T1 no link}} ===
 +
You can run the PorchBoard into T1® Channel 4 or 5, completely flat, no effects. While you could use T1® Channels 1, 2, or 3, there is no need to do that, so you can leave 1, 2, and 3 available for other inputs that require more gain.

=== {{Classic}} or {{Model I}} ===
 +
On a {{Classic}} or {{Model I}}, you may use Power Stand Channel 3 or 4.
 +
=== {{Model II}} ===
 +
You can also run the PorchBoard directly to a {{Model II}} [[L1® Model II#Analog Input|Power Stand Analog input]]. You would use the Analog trim to control the volume. If you don't mind doing that, this leaves another input on the {{T1}} available.
 +
 
 +
=== {{Compact}} ===
 +
The PorchBoard works well with the {{Compact}}. If you are not using Channel 2 for a different instrument then run the PorchBoard &frac14; inch output to Compact Channel 2 - &frac14; inch input.
 +
 
 +
If you are using Channel 2 for Guitar or other instrument then you can run the PorchBoard to one of the Channel 2 RCA jacks using a &frac14; inch to RCA adapter or cable.

== Playing the PorchBoard through the L1® ==

Like any instrument, when you spend some time with it you can get different effects and be more expressive with it as you learn its capabilities & limitations .
 +
 
 +
* With the new model, there is a shorter sensor rail and more consistent sound across the length. With older models you could get more variation of volume depending on where you placed your foot. With the newer model, you can moderate the volume by how hard you tap with your foot.  
  
 
* While sitting ''(which makes it *much* easier to use both feet!)'', I found it effective to place one foot over one end of the tap rail (over the support on one end) while the other foot did the tapping at various places.  This acted something like a "damper" pedal/muffler, allowing me more control over how quietly I could 'tap'.

* As with many percussive instruments, you definitely get different sounds when you do a "stomp-and-leave -the-foot-on-the-rail" vs. a "quick-tap-and-get-the-foot-off-as-fast-as-you-can".

* There's no reason to just tap with just the toe or ball of your foot.  You can also turn it around to place the toe rail (the one with the pickup under it) under your heel, so you tap by raising your heel rather than the toe.  In a lot of ways that is often a more comfortable position for me when I'm playing the keyboard (raising the heel rather than the toe).  Besides that, it uses different muscles -- so when my leg is getting a bit tired, I'll sometimes turn the PorchBoard around before the next song.

* It is designed to produce a tone in the 33-100 Hz range (very low). The 33 Hz (with a strong 99 Hz harmonic) was selected because it offers a strong supportive bass "thump" in any key- similar to a large marching band bass drum. Often the nature of the sound tends to resemble a note when another instrument (such as a guitar) suggests a note. <ref>Nature of the sound....

 +
* Since the PorchBoard produces predominately low-end sounds it is subject to the same issues that can arise with any instrument that works in the low bass ranges. See: [[Bass Regeneration]] for more information. <br />Because the PorchBoard does not make any audible acoustic sound, and it does not use a resonant surface<ref>the PorchBoard does not use a resonant surface for pickkup [http://porchboard.com/FAQ02.html PorchBoard FAQs]</ref> to pickup the sound, it does not contribute to low end feedback in a live music setting.

* When using the PorchBoard with a {{Classic}} or {{Model I}} use at least one {{B1}} as you would with any instrument that plays bass notes. The sound of the PorchBoard comes through well with the {{Compact}} but sounds deeper with the {{L1 nl}} models that have a {{B1}}.

 +
* The PorchBoard is uses a proximity sensor originally designed for the automotive industry rather than a musical instrument pickup<ref>Proximity Sensor [http://porchboard.com/FAQ01.html PorchBoard FAQs]</ref>.

=== Instructions ===
 +
This is included here because it gives insight into the different models. From the [http://www.porchboard.com/Instructions.html PorchBoard site]
 +
 
 +
The PorchBoard Bass plugs directly into an amplification system (set up much like a bass guitar would be.)using a quarter-quarter guitar cord or an XLR cord (or both simultaneously).  No additional power sources or batteries are required.
 +
 
 +
Beginning tapping (heel on heel rail and toe on suspended toe rail) with a very simple beat, tapping once or twice each measure.  With a little practice you will develop your own style and rhythm and your PorchBoard playing will become automatic.
 +
 
 +
Adjust the amplifier controls for tone and adequate volume.  We suggest using a maximum setting on the low end (bass) control and then adjust the volume control so that a good sound is achieved with minimum tapping effort.  Extreme tapping efforts are not necessary.
 +
 
 +
The PorchBoard is designed to produce a tone in the 33-100 HZ range (very low).  The 33 HZ (with a strong 99 HZ harmonic) was selected because it offers a strong supportive bass "thump" in any key- similar to a large marching band bass drum.  Often the nature of the sound tends to resemble a note when another instrument (such as a guitar) suggests a note.
 +
 
 +
Excellent results can be obtained by using a quality bass amp, keyboard amp, capable PA system, powered subwoofer (the PorchBoard has adequate output to drive most powered subwoofers without the use of a pre-amp or any amplification system) that can reproduce these low frequencies at adequate levels.
 +
 
 +
The PorchBoard has a three way frequency response switch designed to match the frequency range of an increased number of amplifiers with higher frequency sound capability.  The L (low) setting allows the very low bass, perfect for subwoofer or quality bass amp usage.  The M (mix) setting filters a mix of low and high frequencies, and the H (high) setting provides for high end, stompbox slap.
  
* There's no reason to just tap with just the toe or ball of your foot. You can also turn it around to place the "tap-rail" ''(the one with the pickup under it)'' under your heel, so you tap by raising your heel rather than the toe.  In a lot of ways that is often a more comfortable position for me when I'm playing the keyboard ''(raising the heel rather than the toe)''.  Besides that, it uses different muscles -- so when my leg is getting a bit tired, I'll sometimes turn the Porchboard around before the next song.

 +
This is the way you usually assemble a PorchBoard.
  
* One can get '''really''' quiet taps by tapping on the "fixed" rail, rather than the "tap-rail"; that is, tap so the vibration goes through the whole board to the pickup, rather than tapping on the "tap-rail" itself ''(which is directly over the pickup)''.  This effect, however, may vary widely, depending on which model of the Porchboard you have.

Besides, why should guitarists be the only ones who have fun with deliberate distortion?!?!
+
==== Reversed ====
 +
Try assembling your PorchBoard like this and the connectors will be protected. This takes a little less floor space. Just disassemble the PorchBoard, rotate the large section 180&deg; and reassemble. The distance between the heel rail and the sensor rail is about 3/4" longer when you do this.  
  
''(Of course, for those of you who have seen Cliff Hendrickson play the keyboard, if one stuck the Porchboard under *his* foot you'd have to turn the gain waaaayyyy down! -- come to think of it, you'd really need two in order to stick one under each foot!)''

* Unlike an acoustic kick drum, or most other large drums, the Porchboard seems to have few strong higher harmonics; for example, turning the High EQ way down seems to have little effect on the resulting sound.
 
  
* Also unlike an acoustic kick drum, the Porchboard has very little intrinsic sense of "pitch" -- little sense of "playing a note".  What that means is that when you play it by itself, it is rather bland and boring.  The '''good''' aspect of that, however, is that it will complement most anything playing along with it -- you never have to "tune it up".
 
  
* Because of producing predominately low-end sounds, it really demonstrates some of the "curses" of bass sound which Hilmar-at-Bose talks about -- such as how the volume of bass sounds can vary radically at different positions in the room.  For example, at one point during an "acoustic jam", someone came up and turned down the volume a bit on the remote channel for the Porchboard, whispering to the performer "it was way too loud in the back of the room" -- but from where the performer was sitting the sound seemed to be nicely "underneath" the other folks playing.
 
  
* The best sound of the Porchboard seems to come when played through an Extended Bass {{L1}} System (one with 4 {{B1}}'s); four {{B1}}'s provide the broad dynamic low range which can bring out the variety of volumes one has with most percussive instruments.  However, it can also sound just fine through single or double {{B1}} Systems, too.  However, it is not recommend for use with an {{L1}} without at least one {{B1}} attached.

* Note that the pickup in the Porchboard is much like a microphone; however, since it is (usually) sitting on the floor, you might need to be careful about what other pieces of electrical devices are near it.  For example, a "wall-wart" ''(an external power supply or transformer)'' next to it might cause a 60-cycle 'hum' to be amplified!

Musical Instrument (Percussion)

The PorchBoard Floor Bass is a simple percussion instrument designed to be tapped by a foot to provide a "kick drum"-like sound. It could be classed as an instrument of indefinite pitch containing complex frequencies through which no discernible pitch can be heard.[1]

With very little audible sound by itself, the internal pickup provides both 1/4" and XLR output connections that may be used simultaneously.

  • The RP PorchBoard was introduced in January 2010. It replaces all previous models including all the features of all previous models in a smaller package.




Settings on the L1 for the PorchBoard

T1 ToneMatch® Audio Engine

You can run the PorchBoard into T1® Channel 4 or 5, completely flat, no effects. While you could use T1® Channels 1, 2, or 3, there is no need to do that, so you can leave 1, 2, and 3 available for other inputs that require more gain.

The ToneMatch® settings are

  • Category: Utility
  • Preset: Flat

L1 Classic or L1 Model I

On a L1 Classic or L1 Model I, you may use Power Stand Channel 3 or 4.

L1 Model II

You can also run the PorchBoard directly to a L1 Model II Power Stand Analog input. You would use the Analog trim to control the volume. If you don't mind doing that, this leaves another input on the T1 ToneMatch Audio Engine available.

L1 Compact

The PorchBoard works well with the L1 Compact. If you are not using Channel 2 for a different instrument then run the PorchBoard ¼ inch output to Compact Channel 2 - ¼ inch input.

If you are using Channel 2 for Guitar or other instrument then you can run the PorchBoard to one of the Channel 2 RCA jacks using a ¼ inch to RCA adapter or cable.

Playing the PorchBoard through the L1®

Like any instrument, when you spend some time with it you can get different effects and be more expressive with it as you learn its capabilities & limitations .

  • With the new model, there is a shorter sensor rail and more consistent sound across the length. With older models you could get more variation of volume depending on where you placed your foot. With the newer model, you can moderate the volume by how hard you tap with your foot.

Beginning tapping (heel on heel rail and toe on suspended toe rail) with a very simple beat, tapping once or twice each measure. With a little practice you will develop your own style and rhythm and your PorchBoard playing will become automatic.

Adjust the amplifier controls for tone and adequate volume. We suggest using a maximum setting on the low end (bass) control and then adjust the volume control so that a good sound is achieved with minimum tapping effort. Extreme tapping efforts are not necessary.

The PorchBoard is designed to produce a tone in the 33-100 HZ range (very low). The 33 HZ (with a strong 99 HZ harmonic) was selected because it offers a strong supportive bass "thump" in any key- similar to a large marching band bass drum. Often the nature of the sound tends to resemble a note when another instrument (such as a guitar) suggests a note.

Excellent results can be obtained by using a quality bass amp, keyboard amp, capable PA system, powered subwoofer (the PorchBoard has adequate output to drive most powered subwoofers without the use of a pre-amp or any amplification system) that can reproduce these low frequencies at adequate levels.

The PorchBoard has a three way frequency response switch designed to match the frequency range of an increased number of amplifiers with higher frequency sound capability. The L (low) setting allows the very low bass, perfect for subwoofer or quality bass amp usage. The M (mix) setting filters a mix of low and high frequencies, and the H (high) setting provides for high end, stompbox slap.

Alternate Assembly

The following pictures are viewed from the player's perspective.

Normal

This is the way you usually assemble a PorchBoard.

Reversed

Try assembling your PorchBoard like this and the connectors will be protected. This takes a little less floor space. Just disassemble the PorchBoard, rotate the large section 180° and reassemble. The distance between the heel rail and the sensor rail is about 3/4" longer when you do this.
