| TouchStripConfiguration property | Behavior if false | Behavior if true | Remarks |
|---|---|---|---|
LEDsControlledByHost |
controlled by push | controlled by host | LED values received from the host are ignored if this is set to false (default behavior) |
hostSendsSysex |
host sends values | host sends sysex | Host sends position values or sysex commands for full control of LEDs. |
valuesSentAsModWheel |
values sent as mod wheel | values sent as pitch bend | Controls whether lights are controlled by sending pitch bend or mod wheel messages. Ignored if hostSendsSysex == true. |
LEDsShowPoint |
LEDs show a bar | LEDs show a point | |
barStartsAtCenter |
bar starts at bottom | bar starts at center | |
doAutoReturn |
auto-return disabled | auro-return enabled | |
autoReturnToCenter |
auto-returns to bottom | auto-returns to center | Ignored if doAutoReturn==false. |
| (defaults indicated with bold) |
LEDsControlledByHost
If LEDsControlledByHost==false, the touch strip hardware sends the value both to the LEDs hardware as well as to the host, simultaneously. Values received from the host are ignored.
If LEDsControlledByHost==true, the touch strip hardware sends position values to the host only. It is the host's responsibility to update to the LEDs while in this mode.
hostSendsSysex and valuesSentAsModWheel
If the LEDs are controlled by the host (LEDsControlledByHost==true), then the host may send commands as
position values or as sysex commands for full control of pitch bend LEDs.
If hostSendsSysex==false, the host may send pitch bend (if valuesSentAsModWheel==false) or mod wheel (if valuesSentAsModWheel==true) to indicate position with the LEDs. The sysex command "setTouchStripLEDs" is ignored while in this mode.
If hostSendsSysex==true, the host may call "setTouchStripLEDs" to set the LEDs. Pitch bend or mod wheel are ignored in this mode.
LED 0 is the bottom LED, LED30 is the top LED. The LEDn values are brightness ranging from 0 to 7.
| Binary | Hexadecimal | Decimal | Configuration | Typical Application |
|---|---|---|---|---|
| 1101000 | 0x68 | 104 | Default: Push 2 controls LEDs as single point with autoreturn to center, sends pitch bend | Pitch bend control |
| 0001100 | 0x0C | 12 | Push 2 controls LEDs as bar starting at bottom, no autoreturn, sends modulation | Volume control |
| 0000011 | 0x03 | 3 | Host controls LEDs using Sysex, Push 2 sends pitch bend | Drum rack MIDI range selection |
