A MIDI Sequencer To Be Proud Of

MIDI sequencers are surprisingly expensive, making them an excellent target for [RH Electronics] who has created a sixteen-step device. It supports up to eight playable parts per step, which can be either MIDI or drum triggers.

The case and front panel are built to a very high standard, and on a piece of stripboard within lies an ATmega644 which does all the MIDI work, an ATmega328 that runs the many LEDs, and an ATtiny85 that reads the front panel buttons. The whole is kept in sync by a timer on the 644 set to produce the required MIDI clock. There is an LCD display too, which carries the status and programming interface.

You can see the result in the video below the break, in which the sequencer is put through its paces alongside a tantalising glimpse of a matching synthesiser. Is this another project, or a commercial device on which Google fails us when we try to find it? Meanwhile this is certainly not the first MIDI sequencer we’ve brought you here at Hackaday, this Arduino one is another example of several also using Atmel parts.
