Tš-L from Instruo is an analog oscillator with triangle core and accurate 1V/oct tracking. Primarily Tš-L offers sine, triangle and square respectively sub-oscillator outputs. If that's not enough, don't worry: the Waveform Crossfade parameter bends eg. the triangle so far that rising and falling sawtooths are also possible. The parameter carves corners and edges out of the clean sine, which gives the sine a metallic character. The pulse width modulation produces the known results and it sounds simply good. In addition, the module includes a wavefolder that taps the sine waveform internally and outputs it to its own audio output. Thanks to the LFO mode, Tš-L is also a versatile modulator far below the audible range.
