Digital Waveform User Oscillator for Korg Minilogue XD, Prologue and NTS-1 

Thank you so much 🙏 Good question. It's been a very long time since I programmed user oscillators. I'm totally out of practice! But to be honest I got a bit frustrated with Korg, I invested a huge amount of time developing my "DW" and "VS" user oscillators, and then Korg came out with their all digital modwave synth which has so many features that overlap with what I developed. Unfortunate coincidence of course! But their lack of interest in taking the prologue and minilogue XD any further forward was also a big factor. Why invest time inventing digital synth capability for their ageing line-up of "logue" synths if the very next month they might wipe you out with yet another all digital product that duplicates what you developed? If I see serious investment in the user oscillator concept again from them then I'll definitely reconsider, it was such a great concept and I am sure it boosted sales for them immensely.

@@TimShoebridge cost/benefit. They have too much to push out In hardware they don't make subscriptions on. What you did certainly isn't wasted. Your knowledge and sharing will inspire, we are just in a period of time where the Taiwan/China things happened chip shortage if you believe that, pandemic if you believe that, inflation, copyright infringement, and good ol pressure to release hardware every other quarter. They did a nice thing calling it used multi engine and you don't have to pay them for their support, but with subscriptions they could do it like Roland cloud /zenology and support development with those funds so it doesn't get so obsolete. These manufacturers are just like car companies. They'll let your infotainment center get 8 years old and it aggravates people that have over the air update capability.they never do updates and keep your car from depreciation , the good thing is synths are trending as investments where as I said, more programmers will do what you did just have to wait for those kinds of people who are musicians and nerdy types with spare time and funds.

It's a pity that you can also not assign external MIDI CC for USER OSC parameter control (AFAIK).

Yeah, I'd love to be able to modulate parameters on a couple of these things. I think they didn't foresee just how much people would actually use them and make really deep oscillators

Use a behringer midi controller with all the like 32 knobs. Or AKAI has a few too

purchased - very happy with this, extremely useful to have in the xd and good value too.

Absolutely! I just bought a minilogue XD and I'm thinking about selling my ESQ-1....hmmm...

Thanks a lot Thorsten. I actually got a bit misty-eyed when I was recording it =D

Can imagine I had a DW8000 in end 90s

Matt B Thanks Matt. I will endeavour to put together a video that demonstrates how to create a DW-8000 kind or organ, EP, pad and acoustic piano. The synth architecture is straightforward once you know which waveforms to choose and in what amounts 👍

Thanks a lot. You can modulate the pitch with both the envelope and the LFO. The LFO can do single shot mode if you don't want a cyclic effect. I think on the patch in the video I used the envelope as it wasn't in use for anything else.

The UI and the processing power :( I did actually prototype an additive oscillator many months ago but it was just too much overhead for the processor...

Not sure if this fits the bill as I only just heard of it myself but @hammondeggsmusic makes an amp simulator called Cabernet, I saw something about using a nts-1 as an amp simulator for portable guitar practice, but I assume it could possibly do what you describe on the XD

@@s3nsec0rruptr80 yooo thank you for the tip! I'll check that out. Sounds like a good solution

That would be cool but first I'd need an ESQ-1 :(

@@TimShoebridge No need for the original ESQ-1 when you've got this famous webpage: www.buchty.net/ensoniq/ I think it has everything you'd need: great sounding SQ80 emulator, original SQ-80 waveforms, etc.

Yes the B control is the same as shift+shape on an XD

@@TimShoebridge oh thank you! I will buy the bundle this afternoon its absolutely stunning! Are you programming it from Scratch or with a Software like Wave Creator? :)

@@FeLix-qi7ci Thanks a lot! Everything needs to be programmed from scratch, no shortcuts unfortunately...

@@TimShoebridge truely amazing. I've got deep respect for this effort! Hope you keep on working on those OSC's. I really think they make the NTS-1 such a powerful device.

Unfortunately it does. I simply did not have any room to hold multiple copies of the waveforms which would be needed in order to simplify the higher octave waveforms. I was working on a smoothing algorithm but it ate up too much processing and I couldn't get it to work. I haven;t given up on the idea but it might take me a while to get something that works. If I do, then I'll provide it as a free upgrade to anyone who has the bought the oscilator.

@@TimShoebridge I thought the DW8000 generated the additive waveforms in real time. Maybe you can use an additive algorithm

@@jackcimino8822 From what I have managed to find out the waveforms are pre-sampled inside the DW synths. At higher octaves some samples are skipped. Additive would be great, I did actually prototype an additive oscillator about a year ago, trouble is it needs a lot of processing power (to generate all the necessary waveforms) that the Korg's multi-engine isn't able to provide :( PS From the questions you're asking I think you're going to be interested in the oscillator I have in development right now. Hopefully it will be ready for release in the next couple of weeks...

@@TimShoebridge Sounds great! I also hope you can add a shift sync or shift ringmod to the dw oscillator
