Low Frequency Expander 2.0 by Yorick Tech

"Announcing the Low Frequency Expander 2.0, a major firmware upgrade, free to all users, available from December 2020.

The LFE is a standalone, hardware modulation expander that supports the OB-6 and Prophet 6, Korg Prologue, Nord Wave 2 and a generic ‘CC-Synth’: any midi device that can be controlled by midi CC messages. It uses midi to provide 3 complex global LFOs and a 6-stage envelope – which can also be configured as an 2 to 16-step modulation sequencer – to add considerably more complexity, movement and playability to these amazing synthesizers. It also acts as a 4-slot modulation matrix, allowing you to route velocity, key, aftertouch, mod wheel or CV in (optional) to about 50 destinations in the synth (80 with the Nord!)

Simply selecting a new patch on the synth makes the LFE automatically recall the same- numbered LFE patch from its memory, so the two have their patches locked together. You can select the next (or previous) patch in the same category, stepping through all of the Bass patches for example.

New in 2.0
Support for the Rev 4 Prophets 5 and 10, and Moog Voyager. CC-Synth and any two synths are included free; others are extra cost.

Internal midi clock for controlling the LFE and external devices.

The synth’s patch names can now be read and displayed by the LFE, so if you edit patches using for example Sound Tower, the LFE can get these directly form the synth even though the synth itself can’t display them.

Release Aftertouch (RAT) allows you to fix an aftertouch value just before releasing the last note and hold that value until the next note is played. This can be used in a similar way to release velocity, which is sadly only generated by a few keyboards. RAT lets you, for example, increase Release times or increase FX depth just by giving the keys a quick press before releasing them.
The LFE now supports Poly Chaining using any keyboard as master and any synth as slave. The LFE handles all of the note sharing so the attached keyboards simply remain in their normal mode.

You can limit the number of voices played, add a second Sub Voice like a sub oscillator but at any pitch, and can add a velocity offset to the sub voice, so that for example, a second voice a 5th higher comes in only when played with more velocity."
