Here we have a clone of the well-known Kastle mini-modular drum-synth from Bastl Instruments tailored for the AE Modular format. As with the original, many and varied sounds and behaviours can be obtained from the module on its own, but possibilities expand hugely when combined into an AE Modular system.

As can be seen, this module breaks away from the regular AE Modular input/output positions to feel a bit closer to the Bastl original. The purple faceplate will be a permanent feature, just for a change!

Definitely not a conventional drum machine module, but great for discovering glitchy rhythms and sounds!

Unfortunately it is not possible to link product stock levels with those from the regular wonkystuff shop, so there might be times when items are not currently in stock. In these cases I will contact you to update the expected shipping times (which will need to include the manufacturing time of course).

This is not my main job, so shipping has to fit around evenings and weekends — please feel free to contact me if you think things are taking too long!
