Heavily Modded Deep Bass Nine

Published on Jan 26, 2019 Stereoping

"Demo for my Analogue Solutions Deep Bass Nine (DB9) with many useful mods, drums from Pearl SC-40. It's still not a 303, no. But it's much more useful now.

While the DB9 got a nice CEM3340 oscillator (like Roland's SH-101) there are some 'features' of the DB9 which i did not really love. I made lots of changes to lift it on a more useful level. Some mods are simple like replacing resistors with pots (glidetime, keytracking) or changing values (cutoff range, modwheel range on cutoff). Others need some additional electronic parts (PWM, Octave-switches). The most elaborate was to 'repair' the glide. It is normally engaged by CC#65 and not(!) by legato played notes. I had to add a 2nd midi interface to fix this - for the benefit of an additional feature: permanently activating or 'muting' glide and accent by midi notes sent on another midichannel. The video shows most of the mods. I also offer an article on my website with schmatics and additional infos on all the mods i made on the DB9:
