Thonk Prok Drums BASSDRUM


Prok drums are compact, expressive, morphing percussion modules. Synthesis not samples!

This is the PRE ASSEMBLED Bassdrum, built and tested here at London Modular from DIY kits provided by Thonk. Please allow up to 4 days in build time.

There are four unique DSP drum models in total, the others being
 Snare, Hi-Hat and Clap. They have a 12-bit Lo-Fi crunch with virtual analog patch morphing. There is a software editor coming in 2019 which connects to the module via USB and lets you edit and create new patches live. 

The Bassdrum synthesis engine can take you anywhere from the simple 808 / 909 one oscillator bassdrum sound, to screaming hardcore kicks that combinine four oscillators, two waveshapers and a noise source. You want solid, it does solid. You want banging distorted harmonics you get them too. Use the X and Y controls to find your sweet spot or create ever evolving drums by morphing between patches.

1 Bank = 4 Quads = 16 Patches
But this doesn’t mean there are only 16 sounds. That would be boring. There is a morphing engine which allows you to continuously move between the sounds within one quad. This isn’t just 4 channels being mixed by volume. All the parameters of the synthesis engine are modulated in real time to create a continuously variable galaxy of sound. Each module comes with a full set of patches built into the firmware : just turn on the module, send in a trigger signal and you’re good to go.

4 Red Squares
• Show current morph position
• When changing Quad will flash to show which quad is selected

X & Y Knobs
Control the morph position between the 4 patches in the current quad.

SD Card Slot
Allows you to store and load custom patches. To load custom patches from the SD card hold the button at boot.

Retrigger the sound. Hold down to switch quads.

X & Y CV
The CV inputs only respond to positive signals from 0v to 5v. For full range control from CV leave the knobs at the zero position. CV inputs are scaled across the remaining range from the knobs.

For example if the X knob is halfway then the CV will control X from 0.5 to 1.0 using the full range of CV input.
