The Sequential Circuits Drumtraks drum machine (1984) is never going to be a Roland 808 or 909. But can it bet appreciated for its own merits?
The Sequential Circuits Drumtraks was the first drum machine that supported MIDI. (The Drumtraks can also send DIN sync and clock.) And while the drum pads were not velocity-sensitive, you can control it via a MIDI keyboard and trigger it with different velocities. While the kick sound is a bit thin, the 13 8-bit sounds can be pitch-shifted dramatically, adding some flexibility.
This demo, via retrosound72, demonstrates the Sequential Circuits Drumtraks sounds, pattern record and pattern playback.
