cruncn/pdbj was developed as a laptop replacement for my live performance
rig. It is aimed at running on a RaspberryPi with a Pisound card without a
display. One button click launches the patch and you have:
- simple looper
- stutter / glitch effect
- LFO gate
- low pass and high pass filter sweeps
- reverb
- triple rhythmic delay lines
- shelving EQs
- mixing buss
- mapping of MIDI controller
- MIDI control over synth/drum machine
- Ableton Link sync
Most of the effects are beat sync'd and will follow the tempo. The effects all have parameters that are to be mapped to your MIDI controller.
Computer: pdbj should run anywhere pd and the required externals run.
I develop and play the patch on my MacbookAir under OS X. When performing I run
it on a RasberryPi with a Pisound board. The whole patch
uses less than 20% of a RasberryPi, so I imagine it'll run whereever you like.
Audio: pdbj takes one stereo input and produces one stereo output.
MIDI: pdbj expects two MIDI ports in pd. The first is connected to your
controller. I use a FaderFox UC44, but you
can remap the parameters to your controller easily within the patch.
The second port is your synth or drum machine. I play with an
Elektron Digitakt, but others
will work fine. pdbj sends MIDI clock to this device, and forwards eight
CCs from the MIDI controller to it. On the Digitakt, I have these set up to
be the master volumes of the eight tracks.
pdbj was developed on pd 0.47 vanilla. Eariler versions might work, but haven't been tested at all.
pdbj needs these pd externals:
abl_link~
freeverb~
ggee
These can all be installed from the Deken installer built into pd (as of 0.47).
