"This is same unit as MAM RS3 but under different label. No longer made these are rare and a wonderful filter for your electronic music. You set the centers of 3 resonant frequencies and then sweep around them for beautiful swells and sweeps under control of the internal LFO or outboard CV control...
This is MONO in but STEREO out here's a good description -
Controls
Stereo Pan
The RS3 gets it's "mono in, stereo out" designation from Filter 1 and Filter 3 being panable from hard left to hard right. With the control fully counterclockwise, Filter 1 is panned hard left, and Filter 3 is panned hard right. Moving the control to the center places all filters "right up the middle" basically making the unit mono, and then continuing to full clockwise reverse the position of Filter 1 and 3.
Refering back to Mode 3 of the LFO modulation, note that the modulation of Filter 1 and 3 comes from different sources. This is where you will get the greatest stereo effect from the RS3, and this is where the "Jarre Strings" sound lives.
This control also has an effect over how the RS3 can create a stereo spread when using the Envelope Follower. Again, Filter 1 and 3 are panable across the stereo field, and with the three follower channels each driving a separate filter, there is magic to be had.
Resonance
Controls the resonance of the filters.
Volume
Controls the output volume.
Bypass
Switches between the dry and effected signals.
Bandpass 1
Controls the frequency of filter 1.
Bandpass 2
Controls the frequency of filter 2.
Bandpass 3
Controls the frequency of filter 3.
LFO Rate
Controls the speed of the LFO.
LFO Depth
Controls the depth of the LFO sweeps.
LFO Mode 1/2/3
Mode 1: LFO 1+ to BPF 1, LFO 1+ to BPF 2, LFO 1+ to BPF 3
Mode 2: LFO 1+ to BPF 1, LFO 2 to BPF 2, LFO 1+ to BPF 3
Mode 3: LFO 1+ to BPF 1, LFO 1- to BPF 2, LFO 2 to BPF 3
Env Depth
This is a classic envelope follower which allows for sweeping the pass frequency of the filters. But, there's a twist. The envelope follower does some frequency separation at three ranges, "Low", "Mid", and "High", with a separate follower circuit at the output of each of these "channels".
Env Decay
Controls the decay of the envelope
Env Polarity +/-
The polarity of the signal from the envelope follower is switchable from Postive to Negative allowing for classic Down sweeps, as well as Up sweeps, of the filters.
Man/Ext Modulation Depth
When something is plugged into the External jack, the Manual control becomes an polarized attenuator for the signal. In the Middle position, the external signal will have no effect. Moving clockwise from center will cause the external signal to sweep the pass frequency up, while moving counterclockwise from center will cause a sweep down."
"This is a rack mount TB-303 clone made by NEXT! In the 90’s.
The Spacebass 3.3 has a 100% analog engine and signal path. The only thing digital is the MIDI interface.
I tried loads of 303 clones and found that this one sonically sounded the most like an original. Run it through an MXR Distortion+ and you can’t tell the difference. Instant acid house.
No sequencer on this guy but depending on how you play it via midi you can create cool glides like using the original’s sequencer.
It also has a CV input on the back to control the VCF cutoff. Cool for integrating with you other modular gear."
"This slick single VCO Monophonic Analog Synth was part of the TB-303 'Clone Wars' in the 90's. This is in the same family as the FreeBass 383 and MB 33. Controls are Autoslide, Saw or Square Waveform, Mix with Sub, ENV PWM, Cutoff, Resonance, EnvMod, Accent, Decay, Distortion and Master Volume. It has a On/Off switch, VCF in, Midi in, out and thru. 7 knobs will transmit MIDI cc data. This was handy as I had this mounted above my MPC 2000XL on a bracket and could 'Over Dub' and create some nice motion. All knobs work fine, no scratchy pots. There is some Rack Rash though. Original Power Supply included. I do own a TB-303 and will say this can hold it's own and has more sonic possibilities, more than my FreeBass too."
