"The Freq. knob controls two VCOs inside and makes noisy fat sound.
The VCOs go to VCF which is the analog synth low pass filter(cut off frequency and resonance).
The envelope generator can be used as a LFO can makes lots of shapes of vibration.
Set the shapes of vibration with attack and release ,and repeat it or 1 shot.
6.35mm(1/4 inch) audio Jack
2.1mm 9V DC input(NEGATIVE CENTER)or a 9V battery
Please be sure to use DC(NOT AC)9V NEGATIVE CENTER(NOT POSITIVE).If you are not sure,please ask me anything because the wrong polarity of the adaptor will break the device. "
FREQ.A,B,C,D ,MOD.1,and MOD.2 control some oscillators and make cool sound.
LFO.1 and LFO.2 make weird waves for FREQ.A,B,C,D .
STAB controls the depth of LFO.1 and 2.
This has the noisy pulse circuit inside and make the sound distorted.
The black switch reduce the voltage while pushing it.

"This is the analog circuit drone machine noise box.
4 OSCILLATORS inside have each FREQUENCY KNOBS and ON/OFF(mute)switch.
The tone of FREQ.A and B can be changed with TONE.A.And volume of FREQ.A and FREQ.B control withVOLUME.A.
The tone of FREQ.C and D can be changed with TONE.B.And volume of FREQ.C and FREQ.D control withVOLUME.B.
BALANCE KNOB controls the balance of VOLUME.A and VOLUME.B.

"This is a kit I have developed from a previous project. The original idea was a gizmo for MIDI jam sessions where several musicians might share a common beat clock accessible to all. The same device also does a 6-way MIDI thru/split so its a pretty handy thing to have.
On board there is a PIC16F688 MCU, a 6N138 opto-isolator and a 4050 six-way non-inverting buffer chip. The PIC handles both the beat clock and the MIDI thru, so there is no contention between the two. Power is via a mini USB socket.
I decided to get some PCBs made up and make an inexpensive kit available on Tindie.

"The MFB SEQ-01 needs to be routed to the trigger or sequencer inputs on the SDS-V cards. I had a few options here. One was to connect the sequencer outs to the Simmons’ native sequencer inputs. The other was to hook it up to the trigger or pad inputs. I opted to use the trigger inputs ( counter intuitive, i know! ) because this gave me a gain adjustment on the face plate of the brain for each trigger from the sequencer to the drum module. The SDS-V drum modules are very dynamic and it’s useful to be able to hit them with sequencer trigger more or less to taste..."
"This one is in fantastic condition, no silly mods or hacks juts as it was made in the 80's and that's exactly what you'll get a real authentic sounding synth! There are Velcro straps on the base but can easily be removed if wanted..."

You can see what looks like the top of a couple of Roland System 100m modulars, a Roland SH-7 & MPG-80 controller, Waldorf XT, Elektron Machinedrum and a Madrona Labs Soundplane amongst the gear.
