Vintage Oberheim DS-2A Digital Sequencer S/N 168
via this auction
"Vintage Oberheim DS-2A Digital Sampler S/N 168
Fully tested using a Kenton Pro Solo MkII to provide Gate and CV while driving a Dotcom Modular Synthesizer. The following Gate types were verified:
• S-Trig No Pull-up
• V-Trig Low (+5V)
• V-Trig High (+15V)
All other sequencer functions were tested and proved to be working as designed. A photo copy of the DS-2 user manual will be included. There are some minor interfacing differences between the DS-2 and DS-2A. However, they are operationally identical and the DS-2 manual provides a good description of operation.
Please note that the sequencer provides a Trigger output and does not sustain the notes. The amount of sustain is controlled by the sequenced synthesizer's envelope generators using the decay and release controls. This sequencer records Keyboard CV voltages and the time between Triggers. During playback the sequence rate can be modified with the clock rate control and the pitch can be modified with three selectable transpose controls. This is a hands on type musical tool and is a lot of fun to use."
