The Bastl Kastle version 1.5 combines a complex oscillator and LFO with a stepped waveform generator.
The oscillator section has 3 sound parameters: PITCH, TIMBRE and WAVESHAPE, which are all under voltage control and with 6 different synthesis modes. It has a main output and a secondary waveform output. Both can be used independently or in combination. The 3 synthesis modes available thru the main output are: phase modulation, noise mode and track & hold modulation.
There are 3 additional modes on the secondary OSC output: phase distortion, tonal noise mode and formant synthesis. Each mode utilises one or two oscillators. The PITCH parameter controls the main oscillator, the TIMBRE sets the PITCH of the modulating oscillator and the WAVESHAPE depends on the synthesis mode.
The voltage controllable LFO has a triangle and square output and a reset input. The stepped waveform generator is inspired by the Rungler circuit by Rob Hordijk. It can produce 8 different voltages either in random order or in 8 or 16 step looping patterns depending on how the BIT IN is patched.
Kastle features a headphone output, 2 in/out ports for interfacing other gear and can run on just 3 AA batteries or USB. It is DIY friendly and ideal for beginners in modular synthesis, it will also add some quite unique functionality to any modular synthesiser system. It has a unique digital lo-fi sound and it can be melodic as well as very noisy and drony, soft or harsh. It is designed to be fun on its own but it is most powerful when combined with other modular gear.
