Sunday Soldering: Akai Rhythm Wolf Drum Machine modifications Akai Rhythm wolf is a cheap analog drum machine. It has a nice old school lo-fi sound but unfortunately Akai left out some quite useful features from the standard setup. Today I decided to modify my unit to better suit my needs. Here are the added mods: Added a resistor to the outer legs of the 'Howl' pot to make the range more useful. By default it's pretty much a switch between clean and a completely destroyed signal. I used 33k. Probably even smaller value would do. Added 3.5mm individual output jacks for all drums. The PCB has nicely marked spots where the individual signals are available but it's actually easier to take them from the volume potentiometers directly. The middle leg gives the signal after the potentiometer so volume also affects the individual outputs. It might have been a better idea to take it before the pot so that it would be possible to silence the signal from the main ...
