Tiptop Audio - BD909 Bass Drum Generator

The Tiptop Audio - BD909 TR909 Bass Drum Generator is the first completely faithful recreation of a sound that is among the most known one in electronic music: that is, the kick drum of the Roland TR-909. The makers were careful enough to integrate the module into modern a modular environment as well.

The Tiptop Audio - BD909 TR909 Bass Drum Generator is a recreation of Roland's TR-909 analog bass drum sound generator adapted for modular synthesizer use. The front panel contains all of the controls found on the original TR-909 drum machine, allowing you full control over the sound’s volume levels to mix with other drums and accent levels, decay tune and the envelope attack and decay segments. In addition to those original controls the manufacturers have also added new controls, further enhancing this legendary sound generator. The name might be misleading because, yes in some knob positions you will get the classic 909 kick, but there is way more in there, it's really a little bass drum lab with a lot of sweet spots. it can go low, high/smooth/harsh, and anywhere in between; it can also go weird with the vc inputs. If you are used to the bd808 then this will take a bit to get used to because it is a different beast, although with some adjustment you might get close sounds. the pcb is very dense with a lot of circuitry and it wasn't easy to fit all that in there but it sure was worth the challenge. Features: output level - 0 - 10v original 909 attack control extended 909 decay control for more umphhh

New controls for the oscillator

tuning: attack tune decay tune - these two will have an effect on each other which makes it really cool

global oscillator tune control - this sets an offset for the oscillator, sets the starting frequency for the envelope

vc-tune with attenuator (can go over a wide range) overload knob - might not be everyone's cup of tea, what it does is overload the sine shapers which adds harmonics and some extra punch, it's an aggressive effect.

vc - overload - can be cv or even audio accent in - can be with a pulse or cv 0 - 5v accent attenuator
