Download the Dreadbox & Polyend Medusa synth firmware update

The Medusa Tool software is introducing a more convenient way of flashing your unit and giving you the ability to dump and loading the presets.


- Improved randomization algorithm (differing values, added LFOs).
- Copy the synth voice from one preset to another while the sequence remains.
(While in the grid more press rec and press the load button, the current voice will get copied to the chosen destination).
- Set the Middle C convention for the Grid as a MIDI controller in the config.

- Fixed bug which was causing a freeze on the initial calibration in a specific LFO setting.

- The Live recording mode is now enabled.
- Redesigned initial and calibration functions.
- Edit the step values while the sequencer is running.
- The Grid MPE functionality is now enabled for controlling external gear.
- The Grid pads are now velocity sensitive (with three different velocity curves to choose from - soft, medium and hard).
- New MIDI menu (full bilateral MIDI input/output implementation - including transport, clock, CC communicates & MIDI channels).
- MIDI channel per voice option. Control, play and sequence each of Medusa's voices on a separate MIDI channel form 1 to 6.
- You can now transpose your sequences while they're running by pressing and holding the hold button and indicating the root note on the pads.
- Two new Grid layouts including the "guitar" layout which resembles a classic guitar tune.
- Shortcuts for targeting the ENV to LFO and LFO to LFO rate, wave and amount.
- Notes and Chords are being transposed in a chosen musical scale.
- Note sustain mode when the Hold button is lit (great for drones).
- The separate OSC tunings in P1 and P2 modes are now unlocked.

- Few minor MIDI bugs fixed.
- Repaired scale generator.
- Fixed menu display bugs.
- The highest note on the Grid isn't repeated anymore, just muted.
- X, Y & Z targets are now modulated by the last pressed pad only.
- The AMP as an X, Y & Z pad modulation target in the P1 and P2 modes is now functional (this is dependent from the AMP ENV Amount knob position).
- The backlit of the pads refresh rate while changing the length, scale and root note was increased.
- The FM OSC 1 & 2 knob position was influencing the initial calibration, not anymore.
- The LFO rate wasn't in sync with the external clock (both USB and DIN), fixed.
- The MIDI output was sending out notes two octaves lower, fixed.
- Improved incoming MIDI clock stability.
- Changed filter resonance behaviour.
- Improved startup procedure.
- Better preset loading procedure.
- Back button works in Config now.

Download the Polyend Seq MIDI Step Sequencer firmware update

The Seq MIDI Step Sequencer Tool allows you to flash your unit in a more convenient way and dump/load your presets.

Firmware update history log:

- Notes incoming from the external controller over MIDI input are being automatically transmitted to all MIDI outputs (DIN, USB).

- The issue with populating a track with the use of the Roll knob causing that the manually added steps were muted is now fixed.

- Added compatibility with the new Polyend Seq Tool for firmware flashing and pattern dump/load functionality.

- New Tempo knob functionality. Used with a track button gives access to a per-track tempo divider/multiplier, MIDI channel input, MIDI channel output, MIDI output source (two last positions moved from the Note knob section).
- The start button resets the cue point for all the tracks.
- Added per track step retrigger - click and hold down the Move knob and indicate the step/s on a track/s you want to retrigger from.
- New rolls behaviour, they work on the whole length of a step now.
- Added new roll Velocity Curve - Random.
- Added roll Note Curve - each step in the roll's length will trigger notes in a scale set to the particular track - Flat, Inc, Dec, Inc-Dec, Dec-Inc, Random.

- Toggle on/off of a step with roll attached won't lose the roll parameter anymore.
- All the previous user reported bugs are now removed.
- The increased refresh rate for the incoming MIDI signals.
- Unstable behaviour while on an external MIDI clock in the first phrase was fixed.
