Attached is a picture (extracted from the service manual) of the circuitboard and the points/parts you have to desolder to add single outputs. The HighHats and Cymbal share the same output, so you will get 7 single outputs for Bassdrum, Snaredrum, Claves, High Conga, Low Conga, Bongo and Highat/Cymbal.
– Full velocity control for all 14 instruments
– Velocity controls guiro pitch
– Midi sync (optional)
Guiro pitch is controlled by midi velocity. If you want a fixed pitch, adjust CV-voltage until the desired pitch is reached.
The image below shows the trigger points. You can solder the uniPulse trigger outs directly to these points. An exception is the Guiro, which is connected to the uniPulse CV-out with an additional diode.
This Sequential Tom needed a new power supply. It states to need 15V AC, but after a little bit of reverse engineering it turned out to actually need 2×7.5V AC. It is quite unlikely to find a wall adapter with 2×7.5V AC, so I had to build an own power supply. It is just a (fused) transformer in a case, and a plug attached to a cable that fits into the back of the Tom. Done 🙂
