SISKworks Cassettone modified tape instrument - Knobcon 2026

video upload by sonicstate

"Mike from SISKworks showed us the Modified Tape Player Prototype, a motor-controlled cassette instrument developed from his earlier "poor man's Mellotron" idea.

He explained that the original version uses one continuous tape loop with a constant tone. Five buttons trigger playback, and each button has a knob that tunes motor speed for a different pitch. The newer prototype keeps that five-key approach and adds a Daisy microprocessor for delay, reverb, filter, harmonizer and reverse grain effects.

The control knobs adjust the last effect engaged, and the filter can self-oscillate slightly. The unit also includes a step sequencer with normal, reverse, bounce and random directions. Steps can be switched on or off, and tempo, length, glide and swing are adjustable. A hold mode latches the last key for drone use.

The prototype includes gate, CV and clock inputs, and it is planned for 1V/oct tuning. It can use tape loops or full-length cassettes, but it does not record to tape. Pricing is not set, and the final version is likely to be desktop rather than Eurorack.
