I modified the Roland TR-77V and built a circuit for the Dave Smith Instruments Evolver so that they can be clocked by trigger signals. More here: acreil.wordpress.com/2014/01/15/syncing-drum-machines
The Roland CR-8000 (hi-hat, handclap) is slaved to the Korg KPR-77 (bass, snare, hi-hat) via DIN sync. One KPR-77 trigger output clocks the TR-77 (miscellaneous patterns with spring reverb) in an irregular pattern, while the other is connected to the "register" input on the CR-8000 (switching between two different patterns). The CR-8000's accent trigger output clocks the Evolver (with Ibanez SDR-1000 reverb). I added two overdubs with the Seiko DS-250, processed by the SDR-1000 and Yamaha FX900. Recorded 2013.

![Keytek CTS-2000 (Jeremy Soule - Menu [Secret of Evermore])
Multitracked and heavily processed Keytek CTS-2000 arrangement of the menu screen music from Secret of Evermore. The idea was to do an elaborate dub mix on each track individually. Recorded 2009?
All synths: Keytek CTS-2000
Drums: Yamaha RX5, Yamaha RY30
Processing: Tapco 4400, Digitech RDS 3.6, Ibanez SDR-1000, Roland VP-70, Alesis Quadraverb, Boss PH-1, Peavey T-Max, Dave Smith Instruments Evolver, Alesis 1622

The CTS-2000 has a very steep lowpass filter (about 7.3 kHz) on both output channels. This is located on the front panel PCB, near where the pitch and mod wheels connect. Removing 5 capacitors per channel (5.6 nF, 10 nF, 820 pF, 15 nF, 330 pF) and retuning the VCF trimpots for a higher cutoff frequency improves the sound considerably.
