1 - Blooming Sparkles
Blooming Sparkles chains a reverb with a sonic bloom and a buffer whose playback can be modulated in different ways. The bloom is created with a filter bank running into allpass filters. The output of the filter bank is recorded into a buffer which is played back at various speeds and directions.
Here’s a quick demo:
| Control | Parameter | Left LED | Right LED |
|---|---|---|---|
| Left knob | Room size | ||
| Right knob | Wet/ dry mix | ||
| Encoder button (single click) | Toggle buffer length or sparkle volume | Red = buffer length, green = sparkle volume | |
| Encoder button (double click) | Cycle playback speed (1x, 2x, 4x) | Red = 1x, orange = 2x, green = 4x | |
| Encoder | Buffer length or sparkle volume | Red = buffer length, green = sparkle volume | |
| Left button | Cycle modulation type | Red = normal, orange = reverse, yellow = forward/ reverse, blue = all | |
| Right button | Toggle freeze buffer | Blue = frozen |
Open the patch blooming_sparkles.pd in Plugdata to get an idea of how it works.

2 - Chorus
| Control | Parameter | Left LED | Right LED |
|---|---|---|---|
| Left knob | Wet/ dry | ||
| Right knob | Rate | ||
| Encoder button | Toggle depth or base delay | Red = depth; green = base delay | |
| Encoder | Depth or base delay | Red = depth; green = base delay | |
| Left button | Cycle: Roland, classic, vibrato | Tempo | |
| Right button |

You can also flash the binary file directly to the pedal using the web interface (see the guide to flashing using the web.

3 - Compressor
| Control | Parameter | Left LED | Right LED |
|---|---|---|---|
| Left knob | Threshold | Gain reduction | |
| Right knob | Make-up gain | ||
| Encoder button | Ratio (2:1, 4:1, 8:1, 16:1) | R O G B | |
| Encoder | |||
| Left button | Attack time (ms): 10, 40, 80, 120 | R O G B | |
| Right button | Release time (ms) 10, 80, 160, 320 | R O G B |
The colour of the left LED indicates which value has been selected. So if you click on the encoder a ratio of 2:1 is red, 4:1 orange, 8:1 green and 16:1 blue.
For attack times, red is 10ms, orange is 40ms, green is 80ms and blue is 120ms. Same principle applies for release (see table above).
The encoder doesn’t do anything at the moment.
Open the patch compressor_mono.pd in Plugdata to get an idea of how it works. I have essentially pulled apart the hv.comp~ and adapted it to allow more parameters to be set.
4 - Overdrive
| Control | Parameter | Left LED | Right LED |
|---|---|---|---|
| Left knob | Overdrive | ||
| Right knob | Gain | ||
| Encoder button | |||
| Encoder | Filter cutoff | Filter freq | |
| Left button | |||
| Right button |
