Frap Tools

Notes: Typically creative stuff from Frap Tools, the Bagai offers analogue sample and hold, but crushing and down sampling, but its combination of six interlinked, CV-controlled sections is capable of much more.

Supplier's Notes:
bagai / ba'ga?i / s.m. [modenese dialect, from a late Latin bagagium 'baggage', formed after the late Latin baga, deriving presumably from the Anglo-Saxon bag (see ancient French bague, Provencal bagua, 'bundle'), whose root may be traced down to the Indo-European *pac, 'to tie,' from which also 'package,' 'pact'] - 'thing,' 'thingamabob.' A term used when the actual name of a thing or a person does not come to mind.

A module that is at the same time a clock burst, S&H, audio bitcrush, or fluctuating random voltage generator is indeed a bit elusive to describe in a single word. Even if one tries, some aspects will always be missing.

Why bother, then? Let's just call it "that thingamabob," or better, "that bagai."


Bagai is an analogue sample and hold, bitcrusher, and downsampler for Eurorack systems, also capable of generating clock bursts, fluctuating random voltages, and coloured noise.

It consists of six highly intertwined sections:

A clock with straight and random outputs (yellow)

An analogue noise generator with variable colour (grey)

A bipolar fluctuating random voltage generator (white) with variable rate

A sample and hold the circuit (orange) with selectable time scale, slow for modulation, or fast for audio sampling up to 48 kHz.

An 8-bit quantized version of the orange S&H circuit with variable bit depth (red)

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 Sapel, with the following differences.

Sample and Hold with an 8-Bit Quantiser

Bagai features two stepped S&H circuits with open input (semi-normalled by default to an analogue noise source).

The quantized one has a LSB selector that defines its bit depth, from 1 to 8 bits.
Random Triggers & Clock Bursts

Besides the well-known "main," "more than," and "less than" modes, Bagai also features a clock burst circuit that creates super fast and unpredictable streams of gates that you can combine with the main clock or to any other trigger you want.

Voltage-Controllable Bitcrusher

When used with audio signals, the 8-bit quantized S&H becomes a warm bitcrusher effect with voltage-controllable bit depth!

Dynamic Downsampler

Bagai's internal clock can switch to an audio rate mode going up to 34 kHz. Patching audio signals into the S&H input will transform Bagai into an analog audio downsampler.

Open Signal Path

Lots of semi-normalled connections allow you to use Bagai in infinite ways: cross-patching has never been this fun.

Start and Stop Controls

You can control both the main clock and the clock bursts via external gates. The main clock also features a button to manually hold it.

Analogue Noise

At Bagai's core is a thermal noise generator that feeds the S&H circuit, creating random voltage streams. The noise output features a knob that changes its colour, emphasizing the high or low frequencies.
