Notes: 12HP version of Marbles Random Sampler

Fully calibrated

Notes: F8R is a 8 channel, 16hp control surface for Eurorack

16HP Width, 20mm Depth
Current Draw: +12V 50 mA, -12V 40 mA

Basic Usage instructions:

Front:

Voltage Select switches: Independent for each channel. Does NOT affect MIDI/I2C data

Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s. Do NOT force the LED back in, it should slide in easily, may require wiggling.

Rear:

Power Header: Standard 10pin power cable, there is NO polarity for this connection. It can be connected either way

MIDI Out Header: This is a 4 pin header but only 3 or 2 connections need to be used. To connect to a DIN cable, either GND, 5 (to pin 5, current sink/aka -), and 4 (to pin 4, current source/aka +) should be used. For internal module to module connections, only pin 4 and 5 should be used. The ground pin is only for the shield in a midi cable, it is never connected on a midi input and isnt necessary for the short module to module lengths

I2C Header: 3 pin header to connect to other I2C devices in your rack, this is an unbuffered connection so cable lengths should be as short as possible (20cm/6" recommended). There are 4.7k pull up resistors on this connection

Module Orientation jumpers: There are 3 of these jumpers which determine how the module operates depending on if the jacks are on top or bottom. They will come installed in the position matching your panel but can be changed should you want to flip it. "INV" is Jacks on Top, the white position is jacks on bottom. Changing these jumpers will change the numbering of the faders from left to right (1->8) in both MIDI and I2C and will invert the voltage response (i.e. 10->0V from top to bottom). The jumper is shown in the "jacks on top" position in the pic below. ALL THREE JUMPERS MUST BE IN THE SAME POSITION for the module to operate correctly.

Module Config DIP switch: This allows you to switch between I2C Follower and I2C Leader modes easily. Simply move the switch to the "lead" position and restart the module (you can press the blue reset button once). The other 3 positions are for future expansion and not currently implemented.

Connector for Expander: This connects the F8R to the I/O expander. The cable is attached to the expander. Note the keyway at the top of the part, the connecter will ONLY connect one way

Notes: 6HP Micromodule of MI Warps.

Notes: mBrane is a 4 channel midi to CV interface based on opensource Yarns. The device includes a 1.5m 3.5mm TRS to Midi male cable (Type B). This is the brand new Rev1.1 of the device which now features PSImidi which allows ANY type of TRS midi cable to be used on the input. Type A or B, male or female, all will work.

Running firmware 1.5
Multichannel MIDI to CV/Gate conversion

Yarns is a MIDI interface providing up to 4 channels of very accurate CV/Gate conversion, which can be assigned to up to 4 voices.

In single voice mode, note, velocity, modulation and aftertouch (or other CC) CV are produced, along with a gate, a trigger, and a clock/reset output.

In two voices mode, two channels of note, modulation or aftertouch CV are produced, along with two gates, and clock/reset outputs.

Finally, in four voices mode, four pairs of CV/Gate outputs are provided.

Each voice has a built-in digital LFO to interpret modulation wheel messages as a vibrato; can respond to pitch-bend messages; or can be smoothed with a glide/portamento control - no need for a dedicated module and patches to get the right response from a MIDI keyboard!

Monophonic and polyphonic

The 2 and 4-voice modes are available both in a "polyphonic" and "multitimbral" flavour. The former receives chords from one single MIDI channel and dispatches them to the voices; while the later provides independent monophonic parts - which can be addressed to different MIDI channels, keyboard ranges, or even velocity levels.

Various note priority modes (low, high, last) and polyphonic allocation schemes (voice-stealing, random, cyclic) allows you to fine-tune the CV/Gate conversion to your playing style.

With sequencing and note transformation...

Each part can generate sequences either through an arpeggiator/euclidean sequencer combo; or with a SH-101 style sequencer with step-by-step recording, storing up to 64 notes. The module can sync to an external MIDI clock, and generate a clock/reset output at any subdivisions of the MIDI clock.

...and even more advanced features.

Other unique features include support for microtunings (either through standard MIDI messages or from a selection of historical tunings or indian ragas), just intonation, and an audio output mode which can transform one, two, or four of the CV outputs into simple digital oscillators.

Notes: 10HP Edges Clone with integrated midi interface and PSImidi which allows any TRS midi cable to be used.

MIDI Functionality:

MIDI Learn: Press this button and send a midi note. The device will use that channel as the base channel

MIDI Mode: This button cycles between two operational modes.

1. 4 single voices trigger on 4 midi channels starting on the base MIDI channel (i.e. base channel is channel 2 so the voices are mapped over channels 2, 3, 4, 5)

2. Simple Poly mode where each voice plays on a different note on the same midi channel

Note about MIDI and Gating: The gate is normalled OPEN by the Gate 1 input. This is by design but will also force the gate open when the device is triggered by midi. Placing a dummy jack will break the open normal the gate will trigger via MIDI normally

Notes: The Analogue-only variant can ONLY be used via CV/Gate like the original CMU-810. MIDI is NOT available on this device.

Fully assembled and Calibrated.

The MSW-810 is a faithful recreation of the CMU-810 Monosynth which was designed as a synth expander for the 1983 CMU-800 computer music production system. At its core however, is the tone generator of the MC-202.

Notes: 6HP Micromodule of Opensource Rings

Notes: The Michigan Synth Works SY-1 Drum synth is a full size, exact replica of the Pearl SY-1 Syncussion. Every detail has been replicated from the original board layouts to the mechanical construction. The assembled version has been modernized to use current manufacturing processes while still using the original board layouts and all parts have been carefully chosen to match the behaviour of the original. Case, boards, and I/O Boards are all interchangeable with the original Pearl device

The Syncussion:

The Syncussion is a 2 voice drum synthesizer with two oscillators per voice and six different modes. Five modes mix and modulate the oscillators plus a noise channel. Each voice has controls for TUNE, DECAY, SWEEP amount, SWEEP Speed, Sweep up/off/down, LFO amount, and LFO speed, LFO Shape (Tri or Square), and sample and hold

OSC Modes:

A: One oscillator sound, at this position the regular drum synthesizer sweep can be effected.

B. Sound of one oscillator adjusting the other osciIIator frequency; produces a metallic sound.

C. Sound of a mix of two oscillator outputs; sound is similar to that of a vibraphone.

D. Sound of mix of two oscillator outputs; produces a low to high sweep and is done by hitting pad softly or hard; there is no connection to SWEEP SPEED and SWEEP RANGE

E. Sound of one oscillator adjusting the other oscillator frequency with a mix of noise; produces a sound similar to hitting thin metal.

F. Sound of only noise

Triggering:

The SY-1 is designed to be triggered via drum triggers which output a very low pulse signal. Modern 5V trigger signals (v-trig) can be used, how it i recommended experimenting with simple audio samples or more dynamic triggers. One of the more interesting features of the Syncussion is the dynamic response to the drum triggers and just sending a straight pulse which maxes out the trigger inputs does not do the device justice.

Tuning:

The original SY-1 uses a tune pedal to adjust the pitch of both oscillators while playing. This functionality has been retained in the original configuration but is of limited use without the pedal. The expanded version DOES have per voice CV control (1v/Oct) as well as the MIDI.

MIDI equipped I/O Configuration: This is the same as the expanded i/o configuration but adds MIDI in place of the MOD input. The MIDI responds to velocity to gate level and pitch for each channel. 2 TRS-TS and TRS MIDI cables are included

Trig 1,2 In - MIDI In - Mute - Tune 1,2 CV in - Output 1, 2

The SY-1 ships with a metal base panel but the DIY wood case can be used instead. It is provided UNFINISHED and sold separately.

What's included:
SY-1 Synthesizer
Universal Power adapter (100-240V, 12V DC out, Tip Positive)
MIDI I/O: 2x 1.5m TRS 1/4" Phone to 2x TS 1/4" Phone, 1x 1.5M 3.5mm TRS to MIDI, 1x TRS 3.5mm to 1/4" TRS Adapter

Notes: 8HP Tides version 2

Fully calibrated.

Notes: BLN is a 4 channel audio level converter designed to interface line or "pro" audio levels to modular audio levels. It features 2 independent converters with 2 channels each.

Converter 1: Line level/Balanced to Modular Level

The inputs for the top converter are for converting -10dB or +4dB signal levels (balanced or unbalanced) to +/-5V modular levels. Each channel can be set individually for +4 or -10 using channel 1 and 2 of the DIP switched

Converter 2: Modular level to Balanced Lined

The inputs for the bottom to converters accept a +/-5V modular audio level and converts them to a BALANCED +4 dB or -10 dB audio level. Each channel can be set individually for +4 or -10 using channel 3 and 4 of the DIP switched.

For balanced signals, simply use a 3.5mm TRS to 1/4" TRS Cable or 3.5mm TRS to 3.5mm TRS cable with a 1/4" TRS adapter. Unbalanced signals should use a 3.5mm TS cable

2HP Width, 32mm Depth

Current Draw: 12/14 mA +12/-12

Please note: This devices uses a polarized power cable, please make sure the red stripe corresponds to the white stripe on the board

Notes: This is 2 x opensource branches. The input of channel one is normalled to all other inputs so you can run this as 1 to 4, 2x 1 to 2, etc. Dual Color LEDs on sliders
