Introducing the TOMS909, the warmth of the classic all-analog punchy tomtoms from the TR-909 drum machine further expanding your Tiptop modular music production system.
The TOMS909 contains all three of the TR-909’s original Low, Mid and High tom-tom circuits adapted for use in the Eurorack modular synthesizer format. The module was tested to sound like a fresh machine coming off the assembly line back in the 80’s. To add flavour to the beast, TipTop Audio have extended each tom’s arming range so it’s easier to dial soft bass drums on the lower ends and high-pitched toms on the other. In addition, all three toms are voltage controlled, letting you play the tom’s pitch with CV sequencers like the Z8000, reshape .e tuning with envelopes and LF0’s, and create new metallic sounding percussive sounds using audio rate frequency modulation of the internal analog oscillators.
The toms circuitry is made up of 9 triangle oscillators and a stack of filters, VCA’s, and envelopes which, in total, took about half of the space on the original 909’s circuit board. Utilising the latest in electronic design technology tipTop Audio 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, its 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. On each gate input TipTop Audio 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.
