Footswitch

MIDI Solutions Footswitch Controller:

The MIDI Solutions Footswitch Controller provides a 1/4" phone jack input for connection to a footswitch or contact closure which can be used to trigger MIDI events (for eight footswitch inputs in a single rack space unit, see the MIDI Solutions F8).

Triggered MIDI events are merged with incoming MIDI messages and sent to the MIDI output of the Footswitch Controller.

Triggered event types are programmable and include :

1. Note Setting:

The Footswitch Controller can be programmed to send out a Note-on message of programmable Note number, velocity, and MIDI channel (a single MIDI channel or all 16 MIDI channels) when the footswitch is depressed, with a corresponding Note-off message sent when the footswitch is released. In addition to the above Note, a second Note with programmable Note number and velocity can be sent out simultaneously with the first. 

It is also possible to cause the Footswitch Controller to alternate between sending the Note-on and Note-off messages each time the footswitch is depressed by programming the Footswitch Controller's Toggle parameter to ON.

2. Control Change Setting:

The Footswitch Controller can be programmed to send out a Control Change message of programmable Control Change number, value, and MIDI channel (a single MIDI channel or all 16 MIDI channels) when the footswitch is depressed, with a zero value of the Control Change message sent when the footswitch is released. In addition to the above Control Change message, a second Control Change message with programmable Control Change number and value can be sent out simultaneously with the first. 

It is also possible to cause the Footswitch Controller to alternate between sending the programmed value and the zero value each time the footswitch is depressed by programming the Footswitch Controller's Toggle parameter to ON.

3. Program Change:

The Footswitch Controller can be programmed to send out a Program Change message of programmable Program Change number and MIDI channel (a single MIDI channel or all 16 MIDI channels) when the footswitch is depressed. Nothing is sent on release of the footswitch.

4. Start/Stop:

The Footswitch Controller can be programmed to send out a MIDI Start message when the footswitch is depressed, with a MIDI Stop message sent when the footswitch is released.

It is also possible to cause the Footswitch Controller to alternate between sending the Start and Stop messages each time the footswitch is depressed by programming the Footswitch Controller's Toggle parameter to ON.

See also Footswitch Controller Application Examples for more information on using the Footswitch Controller as an external Start and Stop control.

5. System Exclusive:

The Footswitch Controller can be programmed to send out a System Exclusive message when the footswitch is depressed, and/or another System Exclusive message when the footswitch is released. The maximum length of each System Exclusive message is 20 bytes.

It is also possible to cause the Footswitch Controller to alternate between System Exclusive messages with each tap of the footswitch by programming the Footswitch Controller's Toggle parameter to ON.

 

Other Functions Include:

1. Program Change Increase/Decrease:

When a single Footswitch Controller unit is programmed as a Program Change INC device, a tap of the footswitch causes it to increment its current Program number and send out the new Program value (nothing is sent on release of the footswitch). The Program number continues to increment with each tap of the footswitch until it reaches 127, after which it wraps around to 0. If a Program Change is received by the Footswitch Controller at any time, it will update its current Program number to that value. This is useful when overriding the Footswitch Controller and jumping to other Programs because this new value is picked up by the Footswitch Controller, and the next tap of the footswitch causes it to increment from this new position.

A Program Change INC/DEC function can also be created by programming a second Footswitch Controller or using a Dual Footswitch Controller as a Program Change DEC device and connecting its MIDI Out to the MIDI In of an INC device. When the footswitch of the DEC device is depressed, a special System Exclusive message is sent to the INC device, causing it to decrement its internal Program number and send out the new value.

The above messages can be sent out on a selected MIDI channel or all 16 MIDI channels.

2. Rechannelize Function:

The Footswitch Controller can be programmed to operate as a MIDI Rechannelizing device. In this mode a depression of the footswitch allows you to enter any number of notes corresponding to the MIDI channel you would like to rechannelize to. For example, to rechannelize to MIDI channel 5, depress the footswitch, press any five notes (the notes don't need to be played sequentially, they can be played at the same time to allow them to be entered as quickly as possible), and then release the footswitch. After releasing the footswitch, all incoming MIDI messages are rechannelized to the selected MIDI channel. The Rechannelize function can be applied to messages on a selected MIDI channel, or all 16 MIDI channels. The power-up state is for all channels to pass through unchanged. If you are looking for a product that allows you to set and forget its rechannelize settings, see the MIDI Solutions Router.

An All-Notes-Off message on the current MIDI channel is sent out out on depression of the footswitch to turn off any notes that may still be playing before switching to the new channel. Any notes played on the current MIDI channel while the footswitch is depressed are not echoed to the Footswitch Controller's MIDI Out, allowing you to enter the new channel information without being heard. Also, once a channel has been entered you can switch back and forth between that channel and the original without having to reenter the notes each time.

3. Transpose Function:

The Footswitch Controller can be programmed to operate as a Note Transposing device. In this mode a depression of the footswitch allows you to enter a note corresponding to the transpose interval. For example, to transpose up by a major third depress the footswitch, press the E above middle C, and then release the footswitch. After releasing the footswitch, all incoming MIDI Notes are transposed by the selected interval. The Transpose function can be applied to notes on a selected MIDI channel, or all 16 MIDI channels. The power-up state is for incoming notes to pass through untransposed.

An All-Notes-Off message on the selected MIDI channel is sent out on depression of the footswitch to turn off any notes that may still be playing before switching to the new key. Any notes played on the selected MIDI channel while the footswitch is depressed are not echoed to the MIDI Out, allowing you to enter the new transpose interval without being heard. Also, once an interval has been entered you can switch back and forth between that interval and the original without having to reenter the new key each time.

4. Tap Tempo Function

The Footswitch Controller can be programmed to operate in Tap Tempo mode. In this mode, the Footswitch Controller continuously sends out MIDI Timing Clock messages at a tempo corresponding to the most recent taps of the footswitch. For example, to send out MIDI clock messages at a tempo of 120 bpm, tap the footswitch at 1/2 second intervals. The Footswitch Controller continues to send out MIDI timing clock messages at the current tempo until a new tempo is entered by retapping the footswitch.

5. Note On FIlter

The Footswitch Controller can be programmed to operate as a Note-on Filter. In this mode a depression of the footswitch causes the Footswitch Controller to filter incoming Note-on messages. An All-Notes-Off message is sent on depression of the footswitch to turn off any notes that may still be playing.

The Note-on Filter function can be applied to messages on a selected MIDI channel or all 16 MIDI channels

It is also possible to cause the Footswitch Controller to alternate between filtering/not filtering the Note-on messages with each tap of the footswitch by programming the Footswitch Controller's Toggle parameter to ON. Or the Footswitch Controller can be programmed to filter Note-on messages only when the footswitch is released by programming the Polarity parameter of the footswitch opposite to its normal operation

 

MIDI Echo and Footswitch Toggle parameters are selectable on/off.

The Polarity of the footswitch can be determined automatically on power-up, or programmed to normally-open or normally-closed.

The Footswitch Controller is programmed by sending it MIDI System Exclusive messages.

This can be done easily with the Processors Programming Tools software.

Once programmed, its settings are retained even after power is removed. The Footswitch Controller can be reprogrammed with new settings as often as needed.

The Footswitch Controller is MIDI-powered, and requires no batteries or power supply to operate with most MIDI products.

A MIDI indicator LED lights up when the product is powered and flashes when MIDI data passes through it.

Application Examples:

The MIDI Solutions Footswitch Controller can be used to generate virtually any type of MIDI message. It can also be used to perform additional functions such as Transpose, Channelize, and Tempo Tap. The F8 is essentially eight Footswitch Controllers in a single rack space unit.

A common application for the Footswitch Controller is to remotely Start and Stop an external sequencer or drum machine. Check the operating instructions of the sequencer or drum machine to determine which MIDI messages it needs to receive in order to start and stop; some devices simply require the MIDI Start and Stop messages - in this case you can program the Footswitch Controller to toggle between sending these messages with each tap of the footswitch. Other devices require both MIDI Start/Stop messages and MIDI Clock messages - in this case you will need to use two Footswitch Controllers connected in series (or a single Dual Footswitch Controller, or two inputs of an F8), one programmed in tempo tap mode to send the MIDI Clock messages, and the other programmed to send Start and Stop messages (this setup allows you to tap in the tempo of the song you are about to play before the song is actually started). Or, if the sequencer or drum machine has the capability of responding to MIDI Machine Control messages, you can program a single Footswitch Controller to toggle between MIDI Machine Control Play and Stop messages with each tap of the footswitch (MIDI Machine Control messages are System Exclusive messages).

Quite a few MIDI devices other than musical instruments use MIDI Note or Control Change messages to activate their various MIDI functions. For example, some of the Yamaha mixing consoles require a middle C to activate their talkback function. The Footswitch Controller can be programmed to generate a middle C, allowing you to control the mixing console's talkback remotely. Cakewalk's Sonar offers a key binding function that enables users to control many of its functions by sending it a series of two notes. The Footswitch Controller can be programmed to send out two MIDI notes in succession, allowing you to control many of Sonar's functions such as Start/Stop, Record, even CAL program files.

The Footswitch Controller has some other useful functions such as Transpose and Channelize.
- The Transpose function allows you to transpose to any key by depressing the footswitch, playing any note above or below middle C, and then releasing the footswitch. For example to transpose up by a major third depress the footswitch, play E above middle C, and then release the footswitch. After doing this, all notes received by the Footswitch Controller are transposed up by a major third. An alternate method of transposing without releasing the notes that are currently playing is by using Pitch Bend - the Footswitch Controller can be programmed to send out a specific Pitch Bend value whenever the footswitch is depressed, and reset Pitch Bend to zero when it is released.
- In Channelize mode the operation is similar to Transpose mode, except that the number of notes is stored. After the footswitch is released all MIDI messages are rechannelized to the channel corresponding to the number of notes that were received. For example to rechannelize to channel five, depress the footswitch, hit any five keys, and then release the footswitch.
