Upcoming V4.2 firmware - Idea Box

AuthorMessage
KODAMO
Hi,
We're working on the EssenceFM V4.2 firmware, let's see what is planned:

- High pass filter: the filter is now multimode (low pass/high pass) with the ability to crossfade between them. Crossfade also controllable via the modulation matrix.

- True mono mode at the layer level: the "Exclusion Group" feature can be configured to either soft-cut the notes (current default behavior, it triggers the release stage of the envelopes) or hard-cut (like a true monophonic synth)

- Sync'd Voice Sequencer. That's not about the MIDI sync which is already there, but the ability to keep each Voice Sequencer instance in sync with each other. Since they are independent and per-note based, syncing them all allows you to play chords and anything you want while keeping a clean sound. This feature will most likely be named "Common" to avoid confusion with MIDI Sync.

- Algorithm in the modulation matrix destinations. Using this will dynamically change the algorithm using the 32 included presets.

- Events in the Voice Sequencer can be moved using the main jog wheel

- Tuning override at the Patch level.


We keep looking at your messages to find what is easily doable. More LFO's/feedbacks isn't (most likely), but we're open to ideas!
Have fun with your synth!

Ordered the V2 of the EssenceFM
I also got a Seaboard and getting the Osmose, so for me the question of a good MPE, or even MPE+, implementation is paramount.
EssenceFM seems like the ideal MPE+ synth :)

As I'm playing with the EFM solely nights, my screen is always dimmed for a good amount.
I'm running the latest surface design theme, which I really enjoy. The only drawback there:
The selected bar/row is hard to distinguish from the background... maybe you make the selection slightly more light/distinguishable in color?!
TJontheRoad
Revamp the effects section a bit. Placing the input gain in same window(s) as the effect would eliminate the need to exit the effect window to adjust.

Clock sync for time based effects. Also delay times displayed in milliseconds rather than 0-127 resolution.

:) what a great list! excited for the release. thank you for being so engaged and receptive to the community's feedback.
That mono mode will be killer! And the algorithm control!

Given your note on LFOs and feedback, the only other thing was what was mentioned in the "Free running op phase" Topic.
Is this something which is could be done easily?
Petajaja
Yeah I'm really hoping for that free running phase, for me this makes quite a big difference in the kinds of patches that're possible.
KODAMO
Added to V4.2 after your remarks:

- Free running phase for operators
- Lighter background color for list item selection (more readable)
- Delay times displayed in ms

Clock sync for effects was asked a lot but it's still unsure if that will be in the next firmware, since it's fairly hard to implement.
RB
Great new editions!
-Free running phase... : So is EssenceFM also fully capable to do Phase Modulation PM?

What about getting Feedback possibilities on more operator blocks, right now we are limited to 1 correct?
KODAMO
PM is a way of achieving FM on digital synthesizers. Or we don't talk about the same thing?

Feedback will most likely stay at 1 per voice for performance reasons.
RB
Thanks for the quick response.
Well, in all honesty, I've only been involved with FM synthesis, and then mostly on the analog more simpler side. This will be my first truly deep dive into more operator driven FM style sound designing.

Guess one can make an approximation of more operator feedback loops through using additional voices.

Looking forward to experimenting with this. Even with 32bit there can be aliasing? the manual mention it when using more complex waveforms.
Petajaja
Amazing to hear that free running phase is being added, that's my number one desired feature.

Another thing that'd be really great to have would be an even smaller multiplier for op ratios, currently it goes down to 0.1 but would be great if it went even lower than that for even slower LFO's when using an op as LFO.

Personally my strongest interest in updates lie in features that expand the possibilities of the FM engine, I understand that there's limitations in terms of what processor / memory can handle but I think the free phase OPs is a good example of something (that I imagine is light on CPU?) that can make a pretty big difference to the possibilities. I'm going to study some other FM synths and see if there's anything else small that could potentially be added to the EFM that could make a big difference.

Anyway.. Thanks so much for making this synth Kodamo, it was an instant hit with me from the moment I turned it on :)

EDIT:

I remember thinking whilst making patches that it'd be so great if a single operator could feed into multiple carriers.. Is this already possible and if not is this something that could potentially be added?
Strider
Regarding clock sync for effect, you mean this could be canceled (or just that it will take more time to implement ?)
Giampo
A function that could be added could be to be able to morph between the wav of the operators inside the voice, as happens in the waveform editor, this would help the creation of wavetables ... even if you can already create fade with envelopes, but it's not the same.

Aliasing is more related to frequency than bit depth. The EssenceFM runs at 48Khz, usually complex waveforms will create higher harmonics and aliasing is more easily reached than with sine waves. It's not a bad thing though, it's part of the FM sound and is often used on purpose to make noise or grittier sounds

It's possible of course, you have to use two fingers to create links that aren't possible to do with simple drag&drop. Simply press both operators to connect them together. Some really weird algorithms are possible by creating lots of links!

Regarding clock sync for effect, you mean this could be canceled (or just that it will take more time to implement ?)

We'll release this feature only if it works reasonably well, so it really depends on the results we get.

Would it be possible to add in voicemode a screen showing some parameters for all operators at the same time, particularly Volume, Multiplier and Quartertones. This would make it possible to quickly adjust e.g. the volume and the frequency of each operator without having to switch screens. I think this could be very helpful when designing sounds.
These could be controllable by the six colored encoders (with a possibility to easily switch between volume, multiplier and quartertones)
and maybe it could even be possible to control these parameters by Midi CC messages, so it would be possible to use an external controller to easily adjust these parameters.
This would give quick control over these important parameters a little bit like the new opsix does with its sliders and encoders.

This is not the first time I've disengaged my brain and knowledge whilst typing away a question to a developer - always makes me feel ashamed.
But it does bring forth an other question, can you reduce bit depth at operator level or do other interesting things to bring some sounds closer to MEGAdrive fm and/or older grittier FM engines?

Having 'templates' for MPE would be nice though.
And with MPE+ that is 'heavier' on sending data one wonders when the midi-interface on EssenceFM will be overwhelmed. Still thinking about how using your countrymens Expressive E's Osmose high sensitivity to control EssenceFM...

Yes there is a feature called "Disable Waveform Interpolation" that will disable waveform smoothing, sound will be closer to a Megadrive. Otherwise it's achievable by sound design, by limiting yourself to 4 op per voice, without effects, not using much polyphony.

Having 'templates' for MPE would be nice though.

We'll try too add a few ones. MPE setup is very simple to setup (long press on a patch in performance mode to assign to all parts)

And with MPE+ that is 'heavier' on sending data one wonders when the midi-interface on EssenceFM will be overwhelmed. Still thinking about how using your countrymens Expressive E's Osmose high sensitivity to control EssenceFM...

Most likely the max MIDI bandwidth will be exceeded before the EssenceFM slows down. If MIDI-DIN is too slow use the USB input which has approx double the bandwidth

Now, THAT will be insane!!!

Actually that feature already exists, it was added in v2 firmware a while ago
Kopplog
Doh! ...so true, so true...

* Is 14-bit midi CC on the cards? Could be via NRPN or SYSEX.

Discarded
What about USB audio? Would be nice to have something like overbridge. Just saw that the hardware doesn't allow it.
KODAMO
USB audio isn't possible on the EssenceFM. That's something we are considering for the VFM keyboards since it's a totally new design.

Do you have examples of hardware/software that take advantage of 14-bit MIDI CC ? That could be useful, but we need to ensure it's used widely enough before spending a lot of time implementing it.
Petajaja
The Motas-6 uses 14-bit midi and you can control it directly via NRPN / lsb/msb but you can also control it via it's editor that can be loaded into a DAW. I overlooked it initially but this editor has proven to be invaluable to me recently and I too would love if we had more control over the EssenceFM like this in the future.

I really love that you're reaching out to the community like this for ideas, this is one of my favorite things about boutique synths like with the previously mentioned Motas, the product just continues to grow into something better and better with time.
Kopplog
+1 on the last post - agreed to formidable open-mindedness to customers!
For real, this was one of the reasons to commit buying your synth - no regrets!
