The dsp-D8 and dsp-L8 drum synthesizer are chips that contains a PCM drumkit in a 28-pin DIP
The D8 have standard drum sounds and the L8 are Latin Percussions.
The chips can be used as voice chips for a drummachine or a drummodule.
They are 8-voice fully polyphonic with 8 separate trig/gate inputs for each voice.
6 of the drums can be separately tuned or modulated by an analog control voltage.
There is an Accent input that boosts all drumsounds by +6dB.
The output is 40KHz 10-bit Sigma-Delta PDM and the chip runs standalone from a
2.7-5 volt power source.
