BeepStreet Drambo

There has been a great deal of interest in it since it was first announced. In recent months, a number of videos have been posted demonstrating its many features. After a long and desperate but also somewhat entertaining wait, Drambo was officially released to the public on April 1st in 2020.

Drambo is a sequencer and easy-to-use modular synth with user sample support. For an FAQ, scroll to the end of this article.
