SoundForce MOD 6 Eurorack Envelope & LFO Module (Black)

We say...

The latest piece of the Eurorack Juno puzzle from SoundForce! MOD 6 combines an LFO and ADSR envelope in one module, with powerful digital control.

Manufacturer's description

MOD 6 is a powerful dual-function Eurorack modulation source. It was designed and developed to complement the other modules in the Juno-themed range of modules: DCO, VCF/VCA 6 and CHORUS 6. It is based on my experiences with the Dual LFO and Dual ADSR modules, with the goal of merging them together into a powerful dual-function next-level module.

Some tech-talk: MOD 6 is using a STM32H743 micro-controller running at 480Mhz. Quite an overkill chip for this application, but the processing power available offers LFO frequencies up to 1khz and high sampling rates on the analog inputs, with CV modulation frequencies of up to 500hz.

The extremely fast processor allows for ultra-snappy ADSR times down to 100us. Another demonstration of the raw power of the chip used is the ability to morph the LFO waveforms using CV. Additionally, thanks to the screen UI, the user can choose the order in which the waveforms will be morphed.

Screen UI

It is the first SoundForce product using a screen-based UI. A small but crisp colored screen was chosen. From the start, the goal was to avoid the dreaded menu-diving user experience. The screen is used to display the module values and for advanced settings only. To keep things clean, a single menu depth is kept at all times.

Parametric CV ranges

The screen and digital UI opened up a lot of new possibilities in terms of user options. In an attempt to avoid the classic CV range mismatch between modules, MOD 6 is implementing an extremely flexible voltage range settings system. Using the screen and encoder, users are able to set custom ranges for each analog inputs and outputs, anywhere between -10V to +10V. This eliminates the need for external attenuator/polarizer modules. The user is able to harmonize CV signals amplitude and polarity between MOD 6 and other modules.
