Have you ever wondered how to generate rhythm on a patchable drum machine that has neither buttons, nor a programmable sequencer? We have and turns out you gotta discover it!

Kastle was originally released in Fall 2016 and gained instant popularity as an affordable, pocket-sized modular synth. We processed a lot of feedback and introduced a much improved version v1.5 a year later. Now we’re revisiting the concept once again with an alternative way to operate the same hardware.

The design process gave birth to a seemingly limited, but in fact an innovative and quite playful take on a rhythm box that is using some novel concepts, like the dynamic acceleration envelope to build “a lot of dynamic rhythm” out of very little modulation.

The Kastle Drum is a special edition of Bastl’s classic mini modular synth focusing on algorithmic industrial glitchy drums.

Drum sound synthesis with a unique dynamic acceleration charged envelope makes this rhythm box surprisingly versatile and extremely fun to play. The built-in VC clock generator with a stepped pattern sequencer can either run on its own or it can be synchronized to analog clock, while retaining the triangle LFO for parameter modulation.

The Kastle Drum is a mini modular synthesizer with a headphone output, 2 in/out ports for interfacing other gear, and it runs on just 3 AA batteries. It is ideal for beginners in modular synthesis, but it will add some quite unique functionality to any modular synthesizer system. It delivers the fun of modular synthesis at a low price and fits into your pocket so you can play it anywhere!

8 drum synthesis styles
”noises” output for less tonal content
DRUM selects drum sounds
acceleration charge dynamic envelope
decay time
PITCH control with offset and CV input with attenuator
voltage-controllable clock with square and triangle output
stepped voltage generator with random, 8 step and 16 step loop mode
2 I/O CV ports that can be routed to any patch point
the main output can drive headphones
3x AA battery operation or USB power selectable by a switch
open source
durable black & gold PCB enclosure

dimensions: 70 x 60 x 50 mm
powered by 3x AA battery or Micro USB
