909 Analog Toms

Introducing the TOMS909, the warmth of the classic, all-analog, punchy tom-toms from the TR-909 drum machine. The TOMS909 contains all three of the TR-909’s original LOW, MID and HIGH tom-tom circuits adapted for use in the modular format. The module was designed to sound like a fresh machine coming off the assembly line back in the 80’s. To add flavor to the beast, we have extended each tom’s tuning range so it’s easier to dial soft bass drums on the low end and high-pitched toms on the other.

The Toms circuitry is made up of 9 triangle oscillators and a stack of filters, VCAs, and envelopes which, in total, took about half of the space on the original 909’s circuit board. Utilizing the latest in electronic design technology, we have managed to squeeze this enormous circuit, consisting of more than 450 components, into an area only 16HP wide. It is a beautiful board with hundreds of tiny, shiny components: it’s a little analog jewel.

Each Tom includes a trigger and accent input with accent level control, manual tune, voltage-control tune input with attenuator and independent audio out. In addition, a MIX out is available that sums all three toms together as well as access to the MIXZ MixBus on the back. On each gate input, we have designed a dual pulse-shaper circuit so you can trigger your TOMS909 with trigger/gate signals from sequencers or any other pulse/clock sources.
