Frap Tools BAGAI

• Analogue random generator, burst generator, sample & hold and down sampler

Clock burst, S&H, audio bitcrush, fluctuating random voltage generator

Bagài is an analog sample and hold, bitcrusher, and downsampler for Eurorack systems, also capable of generating clock bursts, fluctuating random voltages, and colored noise.

It consists of six highly intertwined sections:

1. A clock with straight and random outputs (yellow)
2. An analog noise generator with variable color (grey)
3. A bipolar fluctuating random voltage generator (white) with variable rate
4. A sample and hold the circuit (orange) with selectable time scale, slow for modulation, or fast for audio sampling up to 48 kHz.
5. An 8-bit quantized version of the orange S&H circuit with variable bit depth (red)
6. A clock burst section (green).

By default, it outputs bipolar random voltages and triggers. The voltages are fluctuating, stepped, and quantized with selectable bit depth. The clocks are straight, randomized, or “burst.”

Once you start patching, you can use it as a S&H, audio downsampler, and bitcrusher, with a sample rate of 48 kHz.

All its major parameters are voltage controllable.

It belongs to the same family as Sapèl, with the following differences.
