MicroMIDI May'83

A single-board serial interface that will link any MIDI synth to the Sinclair Spectrum microcomputer. Features include three parallel I/O ports, crystal-controlled data transfer, and opto-coupled output. The PCB is available from EmmSoft at £4.25.

MicroMIDI II

A revised, simpler version of MicroMIDI was published subsequently which incorporated the same facilities with the exception of the three parallel I/O ports. The PCB is available from EmmSoft at £4.25.

As part of the 'Spectrum MIDI'article in E&MM July '84, two software programs were published - a SixTrak Patch Dump and DX7 MIDI Dump - both of which will run on either version of MicroMIDI.

A cassette containing an expanded version of Steve Parr's DX7 MIDI Dump program (including a short sequencing routine) can be obtained from SDS, 18 Cam bait Road, London SW15 6EW, for £5.95 including postage and VAT.

OMDAC June '83

The OMDAC, when used in conjunction with a Z80-based microprocessor, will provide eight sets of gate, trigger and control voltages compatible with most one-volt-per-octave synthesisers.

A 'Patch Change' program for the Spectrum was published in E&MM September '84, while the second OMDAC Update (see elsewhere in this issue) enables the hardware to be modified to run on the BBC B microcomputer.

Further OMDAC software is also in the pipeline.

BeeBMIDI June & July '84

A MIDI interface for the BBC Model B microcomputer, Part 1 of BeeBMIDI contained the technological and constructional details, while Part 2 continued with a full parts list and some MIDI software routines. The PCB is available from EmmSoft at £4.95.

BeeBMIDI Software August '84

A full listing of a comprehensive voice dump program written in BBC BASIC and 6502 Assembler for the Yamaha DX7, with the software also available on cassette (for the sore-fingered) from EmmSoft, price £7.95.

Further software for BeeBMIDI is currently under development. This will include voice dump and MIDI polyphonic sequencing programs.
