Hi Hal,
Probably we/someone should write a wiki entry or something on the new features! The idea is something like this:
The encoders underneath the OLED displays work just as before
The encoder switch functions are in theory freely assignable but are typically used to accelerate encoder data
The first row of illuminated "Soft" keyswitches are equivalent to the GP buttons plus the dual-colour step LEDs of the Wilba version
The second "Selection Row" keyswitches change function depending on the button lit up around the datawheel on the JA board (see below)
These LEDs are also dual colour
The row of Apem/MEC switches should be familiar to V4 users
The RGB Beat LED flashes a different colour for the beat and the whole measure
The JA board has a built-in Activity Matrix and typically displays the track position in a single colour
Other display options like a custom logo or the current BPM can be displayed (both with optional beat flash; also for the TPD)
The datawheel functions as before and has a push function (currently not assigned to anything I think)
The JA board carries the transport controls (play, pause, stop etc.) and a few extras
The Selection Row buttons around the datawheel are:
Step View
Tracks
Parameter Layer
Trigger Layer
(Drum) Instrument
Track Mute
Bookmark
Song Phrase
On the JA board, press and release one of these to change the Selection Row function
Press and hold the JA button to temporarily change the Row function, which jumps back to the previous function on release
On the v4+, all 16 Selection Row buttons are accessible and multiple selections are possible by holding down several buttons simultaneously
Tracks are still colour-coded into groups of four tracks and named identically (e.g. G1T1-G4T4)
On the V4, tracks were chosen with four track groups and four tracks for a total of 16 tracks and only three trigger and parameter layers had dedicated buttons (normally holding Param./Trig. C would bring up the layers menu screen)
Rear panel has a USB B port (power/data) for better mechanical strength
Switch for USB OTG host is provided but we notice some devices are incompatible
Footswitch/gate input (currently not assigned to functions)
Rear panel LEDs:
Green: power
Orange: SD Card available
Red: any received MIDI IN
Blue: LED any transmitted MIDI OUT
I think that's it!
Best,
Andy
