	stg soundlabs .com the .com is a comparator and divider network configured for audio applications. think of it as an elaborate version of the pwm and suboctave of the sh-101. or if you're not familiar with the sh-101, think of it as a little box you can put any waveform into and get a pulse wave and 4 varieties of suboctave from. the signal input is where you would put whatever you want to turn into a pulse wave into. the threshold control sets the "flip" point of the comparator, and has a range of approximately negative five volts to positive five volts. think of it as a pulse width control. the threshold input is summed with the manual control, and allows for external modulation of the threshold point. think of it as a pulse width modulation input. next are five outputs. they are all ten volt peak-to-peak signal to play nice with other audio modules. this is unlike the sh-101, where the suboctave had a dc offset which made its bass frequencies not as strong as they could have been. the first is the direct output of the comparator. in pulse width terms this is zero to one hundred percent. the second output is a 50 percent duty cycle wave one octave lower than the main output. the third output is a variable output, from one to forty-nine percent duty cycle, one octave lower than the main output. the fourth output is a 50 percent duty cycle wave two octaves lower than the main output. the fifth output is a 25 percent duty cycle wave two octaves lower than the main output. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $128.00

	tiptop audio bd808 the bd808 is roland's tr-808's bass drum circuit adapted for use in eurorack modular synthesizer format and was tested to sound like a fresh machine coming out of the assembly line back in the 80's. the adaptation to modular format has allowed tiptop to add some special features such as independent accent levels, a high-powered gain stage, dual input-pulse-shaper and extended decay- all this without compromising the original signature sound of the tr-808. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $80.00
	tiptop audio bd909 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. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $144.00
	tiptop audio cb808 the cb808 is the tr-808's analog cow bell sound generator in eurorack format. just like the other drums in this series, adapting the circuit to the modular format has allowed us to add some special features like pitch modulation, lfo (with control over rate and depth), independent accent levels, a high-powered gain stage, and a dual-input pulse-shaper - all without compromising the signature sound of the tr-808's spacey cow wow. the cb808 sound is generated by two square wave oscillators that go through band pass filtering and then get mixed together. it's a simple analog circuit with a very cool output. what makes the 808 cow bell sound so well known is that it dosen't feel constant, but rather slightly spacey. the internal pitch-modulating lfo that we added takes this effect even further, but stays within the bounds of the 808 sound, keeping it very musical and easy to play with. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $80.00
	tiptop audio cymbl909 introducing the cymbl909, part of tiptop's series of drum modules that brings those classic percussion sounds into the modular synth world, further expanding the tiptop modular drum machine. the original circuits use a combination of low-fi 6 bit sound samples that pass through a series of analog elements that provide envelope and filtering to the source sound. the cymbl909 module adds manual and voltage control of the sample's analog tuning section creating tones which range from heavy industrial at the low end, to the original crash/ride sound at the mid range, and bright hats like sounds at the top end. modulating the tune with an envelope, cv sequencer or lfo makes interesting sound bending effects, which can be applied either in or out of sync with the triggering of the sounds. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $160.00

	wmd phase displacement oscillator mk1 this hybrid vco has all the feel of an analog vco but with the benefits of digital waveshaping. the pdo will easily find a home in your system! the pdo exists to utilize the phenomenon of phase modulation (pm). this allows for the relative phase difference of its outputs to be set or modulated, producing very interesting sounds. the result is similar to frequency modulation (fm) but affects the output to a greater degree without affecting the stability of the initial frequency. pm has the same benefits of quadrature filters/sine wave generators and greatly exceeds their capabilities at audio rate modulations. pm is highly useful for for creating metallic and bell tones and very controlled harmonic interactions. because pm affects the relative phase and not the frequency of the waveform generated, the pdo can self modulate its pm inputs. thils creates complex harmonic signals that seem to vary in frequency but are quite stable. phase modulation is also quite powerful when using the pdo as an lfo. adjusting the relative phase of each output allows for very precise modulation of other modules. each output can have any of the available waveforms simultaniously. there is a myriad of modulation possible with the pdo! the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $340.00
