Synth modules

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: 8HP Tides version 2

Fully calibrated.

Notes: 8HP Tides version 2

Fully calibrated.

With LED Pots for the attenuverters.

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: 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

Notes: 6HP Micromodule of MI Warps.
