PAiA | Theremax
|Since its introduction during the 1920's the instrument which bears Leon Theremin's name has been evocative in image and tone. PAiA's Theremax theremin captures this spirit in an instrument based on the same heterodyne principles as the original but with embellishments made possible by the economy of integrated circuits and solid state electronics.
In addition to the traditional mellow sine-like tone, Theremax's Timbre control can mix in a harmonic rich square wave to produce a signal that's ideal for use with external filters and processors. And to control outboard units, there are Pitch and Volume Control Voltage outputs.
But the features that really set Tmax apart as a gestural controller are it's Velocity Control Voltage (proportional to how fast you increase the Volume) and Gate/Trigger outputs. A convenient foot switch input allows muting the internal tone source without disabling the CVs.
Panel Controls are conveniently grouped at the front of the instrument to minimize unwanted interactions during set-up. Tech-heads will appreciate the use of four r.f. oscillators to maximize sensitivity and provide wide dynamic range, as shown in the schematic and design analysis.

|Velocity||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.||Aftertouch||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.|
