PControl Modular Part#3 – TH custom effects

Its been a long time since the last post but I’ve been working on it again in the last 3 months.

Everything is tested but the MIDI part and everything works fine so far.

Here is the current 20-loop prototype (backside):

From top to down and left to right:

Things to do:

Verify MIDI functions
Change processor to a version with more programming memory (The fonts for the graphic display are a little large compared to the rest of the code)
Remove some bugs from the code that have to do with storing information
Do documentation ! 🙂
…

While working on the code the final specs come to light:

Full modular design
- auto detection of display type
- auto detection of extension modules connected
- piggiback mounting of control boards (switches and indicators)
Minimum solution has 5 loops, expandable in steps of 5 up to 20 loops
There are three display variants at the moment
- 3 digit 7-segment LED
- 132×32 LCD Module with backlight (DOGM-132)
- OLED 128×64
120 presets that can be organized as
- 24×5
- 12×10
- 8×15
- 6×20
Each preset stores
- 20 loops
- 12 letter preset name
- 16 bytes of midi data to be sent
Switching options
- Tuner out
- Mute while switching (configurable mute time)
- standard loop-switch
- opto loop-switch
- amp selector
- amp channel switching (TS/TRS)
- loop order switcher
- stereo option
- switching of “before amp” effects and “amp send/return effects” in one setup
- MIDI switching of external effects and amps
  - Program Change (selectable channel and program)
  - Control Change (selectable channel, control and value)
