Radias Wishlist:
• I would love to be able to browse/audition for new timbres in a Timbre slot within a Program without it stopping the playback of all the other three Timbres in the Program if they are running. Currently if you want to browse through timbres or switch out a timbre when it is all playing then all playback ceases when you switch in a new timbre, and you have to fire each and every timbre all up again to continue where you left off each time.
• Make Pulse Width for pulse/square available for Osc 2. In fact why not make Osc2 a fully fledged oscillator like Osc 1, with all the same synthesis options.

• FM synthesis option to allow the other oscillator to be a modulator (again would be better if Osc 2 had all of Osc 1’s synthesis options too, then the options available as potential FM modulator(s) would be absolutely vast).
• Ability to set initial phase of oscillator(s) on note-on. In fact better phase control between oscillators would be great as the Radias can sometimes have a tendency to sound
overly phasey, I feel.
• At least one more LFO. And faster LFO speeds.
• Ability to link Mod Sequences together to form longer sequences (like you can with the two Step Sequencer[s]).
• Band reject (notch) filter. Am unable to program some of my favourite trance sounds as a consequence of the lack of a band-reject filter.
• User importable/customisable single-cycle PCM/DWGs.
• Smooth interpolation between knob values to eliminate MIDI zipper artifacts. The Access Virus has already been doing this since the late 90's!
• Filter emulations. A nice really dirty MS20 filter. No clean stuff, please!
• I'd like to see more routing options including more sources but particularly destinations.
• Finer oscillator detune ("tune") values. Currently it starts to become really detuned after a tune value as low as 10. Separately, when using unison, detune values beyond 25 are already discordant meaning the further 75 values are potentially going to waste.
• Although Drive/WS can be placed before or after the filters, it would also be nice to be able to place Drive/WS inbetween the two filters for serial usage. Filter1>Drive>Filter2
• Patch compatibility with EXB-Radias (and, within the given limits, R3)!!
• Changing the “Catch” knob mode to temporarily steal LCD display while tweaking a knob before the LCD reverts back exactly to what page and parameter you were editing previously. For example you may be currently setting up some effects (or similar) from within the menus but decide you want to increase the filter cutoff slightly, so you tweak the filter cutoff knob to do so, but then you have to dive back into all the menus again to find the page and parameter in the effects section (or similar) you were editing beforehand.
• Ability to memorise your LCD brightness selection after power down. Currently I have to jump into the Global menu to whack the brightness up to level 9 each time I turn the Radias on.
• Lastly, for a new physical Radias v2, but by no means least, aftertouch and a ribbon controller.
The Radias is already an awesome synth, but I think it could have gone a lot more places. Sadly, in many respects I feel the synthesis engine and options have actually taken a
backward step compared to the Z1/Moss in terms of numbers of main oscillators per voice, available synthesis/oscillator types including corresponding modulation options, quantity of LFOs, dynamic modulation (controllers), even the (un)suitability of ranges of some given knob values, etc.
However the mod/step/arp sequencing is really great, along with the drum and synth PCM samples, great sounding vocoder, analogue-esque 'drive' option for either pre/post filter depending on the effect you're after (very nice to have that option), many of the insert effects (tape echo and grainshifter for the win!), customisable two-band shelving EQ per part, and even little flourishes like the morphing LFOs.

You can actually program your own. (Page 96 in the paper manual)
It has up/down/up&down1/up&down2/chord action, customisable up to 32 steps, programmable trigger/velocity/gate[time] per step, plus configurable resolution, swing function, and a specified octave range.
