Intellijel

Notes: Small and efficient MIDI to CV courtesy of Intellijel's 1U series. Works in conjunction with an Intellijel case or the MIDI IN Jacks 1U module to give you Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset.

Supplier's Notes:
The MIDI 1U system provides all the essentials to control and sync your Eurorack modular from your computer, mobile, or hardware MIDI device with a minimum of fuss. Several of the module's most important features can be changed using the two front panel buttons, with full configuration capabilities offered via the Intellijel Config app, which is available for both Mac and Windows. The connectivity, feature set, expandability, and compact size make the MIDI 1U system ideal for integrating your modular gear with the rest of your rig.

Intellijel's MIDI 1U system comprises several elements, which work together to provide flexible, programmable MIDI-to-CV conversion to your Eurorack modules: The system comprises two mandatory components, and one optional component:

MIDI 1U module - This 14HP 1U module receives MIDI from an attached, external MIDI input connector (7U case, Palette case, or MIDI IN Jacks 1U module), and extracts (by default) Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset messages i sending the proportional voltages to individual 3.5mm jacks for patching.If desired, the CC and MOD jacks may be configured to respond to either Channel Aftertouch or High Resolution CC, and the Reset jacks can be configured as a Run jack, instead. Additionally, MIDI 1U features an alternate Dual Mode, which maintains the Clock & Reset functionality, but uses the other six jacks to transmit Pitch, Velocity and Gate messages derived from two separate MIDI channels.
MIDI input connector - the MIDI 1U module does not have its own MIDI input jack. This enables you to use the MIDI/USB inputs built-in to your Intellijel 7U Performance Case or Palette Case. If you don't own one of these cases, you can purchase the MIDI IN Jacks 1U module to connect an external MIDI device.
MIDI Expander 1U module - This optional 14HP 1U module connects to the MIDI 1U module and adds an additional eight 3.5mm CV outputs. These outputs are fully programmable using the Intellijel Config app, and greatly expand MIDI 1U's ability to control your entire Eurorack system.

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

ADSR + VCA Features

Dual Analogue ADSR envelopes with digital gate Pulser for trapezoid shapes
Pulser stages P1 and P2 can be selectively routed to trigger each ADSR via panel switches
Three timing ranges: (FAST: ~5 seconds, MED: ~35sec, SLOW: ~1min A/D times)
Retrig input (allows re-triggering of the envelope if source gate held high)
VCA input can be used to dynamically control the respective ADSR output level (bipolar) or to process signals to be modulated in amplitude by the ADSR.
Manual GATE buttons for each envelope

Pulser Features

A pulse is made of individually controllable T1 and T2 stage lengths
CV control over T1 and T2 time
Pulser can be one-shot (SINGLE) or repeating (CYCLE)
PULSE output has a switch to select P1 or P2 as the source.
Pulser stages P1 and P2 can be selectively routed to trigger each ADSR via panel switches
START trigger input for starting/restarting the Pulser sequence
Manual GATE button to trigger the Pulser sequence
