Downpoly, a musical project child utilizing the often-overlooked and undervalued Tandy Radio Shack TRS-80 Microcomputer as a powerful synth and sequencer. This project breathes new musical life into these iconic machines, demonstrating their potential to create rich and unique music.
At the heart of Downpoly’s setup are the RadioShack TRS-80 Microcomputers, augmented by two key attachments: the Orchestra-90 and the custom-designed MIDI/80. Developed by Michael Wessel, with some z80 wizardry from George Phillips the MIDI/80 provides essential MIDI input and output capabilities, connecting the vintage TRS-80 to modern musical instruments and software.
The sound is centered around the Stereo Orchestra Organ, a custom 2-row, single-octave keyboard, created by George Phillips. It leverages the TRS-80’s built-in keyboard to control a 2-note software organ, transmitting real-time data to the external Orchestra-90 attachment. The Orchestra-90, a stereo music synthesizer, generates sine, saw, square, and triangle waveforms, with adjustable volume and waveform selection.
The audio output from the Orchestra-90 is bussed through a pedal chain for shaping and effects, normally reserved for a guitar. This chain includes a Dunlop Crybaby Wah, BlackFinger Tube Pre/Compressor, Mutron III, three distortions all processed through different amps and post effects gear like the Memory Man, Super Pulsar, POG3 and more.
The signal is routed through various guitar impulse response (IR) mic/amp combinations, yielding a diverse range of sounds from the single TRS-80 machine. This innovative approach allows Downpoly to create a wide spectrum of sounds, from deep, chorused bass sine tones to screaming, tube-squashed wah saw waves.
The other half of the sound comes from the extreme power of the MIDI/80 and the TRACKER sequencer. The software allows the sequence of MIDI tracks, 6 per pattern that can control modern MIDI gear. Using the TD-6 808/909 emulation coupled with the S2 McFish wave tables, and the Waldorf Blofeld Downpoly creates a unique but post-modern-80s-like-fusion of synth and rythm with the edge of a rock style.
