Just wanted to give a quick update about things going on here at Dove Audio.
Things on Delta have halted for a short while whilst I finish a couple of projects, the NJM2069 Module was one of those and the MuSeq is the next.
MuSeq is significantly behind, basically Dove Audio is just myself, Paula, with the odd bit of help from my partner Jon. I hit a major bug with the MIDI handling in that the library I was using (which seemed to do everything) wasn’t interrupt driven and you had to poll it. Which meant that when syncing to MIDI clock it would sometimes miss clock when switching pages.
Reworking, or refactoring, this took a while. But it’s working. This blow kind of took the wind out of my sales, hence finishing the NJM2069 module first. Now the NJM2069 is out, I am working on the MuSeq again.
I wanted to give a quick update on various projects and so on, so let’s dive into this.
MUSeq Things are going OK with this, I’ve narrowed down a few more bugs, but the MIDI timing bug remains and it’s now significantly behind schedule. Right now the code is split across about three files and the majority of the code is in one huge file. So to make life easier (scrolling up and down a few thousand lines of code isn’t easy) I’ve begun splitting the project into smaller part. For example one file for the UI, one for the file manager, one for clock and so on. Now My coding skills aren’t the greatest in the world, however the ace up my sleeve is that Jon, my boyfriend, is a professional coder. Jon is going to help me split the project into multiple files and get it to compile (my attempts all ended up with hundreds of compiler errors), this won’t be a quick thing, but it will be worth it when it’s done. The layout of the second revision of PCB is planned to start next week with removal of things like the unused display, but the addition of a mode switch and some other small tweaks. So things should be settling down into their final form. My hope is to build another couple of these and get them into the hands of a couple of people to beta test and report bugs/problems to me prior to making these available to buy.
2069 VCF+VCA Things are going well with this, PCBs have arrived and they look fabulous;
We have a small block in that the next generation of panel has been blocked for a while whilst the people making it recover from some COVID related problems. However I plan to start assembling the first 3 or 4 of these this coming week ready for when the panels arrive. So keep your eyes peeled!
Delta Delta is something new, something I’ve been thinking on for a while. It’s a poly synth and I’m happy to report things are going well. I’ve proto-typed the VCF & VCA and I’ve got the basic voice code working. Prototype PCBs have been sent off to be made so further development can be done (somethings you just can’t prototype on strip board). Here’s a Render from my CAD package of the board.
I’m keeping full specs close to my chest right now, I have a clear idea of what I’m aiming for, but until I’ve proven it’s possible and have sound demos I won’t be giving anything away. Rest assured though, there are a number of innovations that will be going into this polysynth. I will also add, don’t expect this to be ready quickly, this is probably 10 to 12 months away from being available to beta testers as there is a lot of work to be done yet. But I do plan on providing updates as things move forward.
Other News In other news, don’t forget we have some Waveplane oscillators left in both Eurorack and MU format and available to buy either Direct or from our dealers.
A number of things have been going on in the world and in my personal life. So I wanted to give a quick update.
The COVID-19 problems are really worrying and very stressful, to see so many people loosing their lives due a disease that can be stopped simply by avoiding social contact is so saddening. Even sadder is that a portion of humanity seem to feel they’re immune, it’s a hoax or simple that it could never happen to them. So they carry on as before resulting in more avoidable deaths. I’m finding the headlines increasingly painful and difficult to read. I can only hope that the selfish people soon wake-up and start acting like responsible adults. One thing is certain, this is a world changing event and our lives will never be the same. I my one hope for this crises is that humanity changes for the better going forward.
A personal update, I’ve recently moved home, this resulted in about 3 weeks of downtime for my development efforts and a lot of upheaval, things are almost back to normal for my working environment.
As a result of my move MuSeq work was on hold, I’ve only just started again. I discovered that the MIDI timing was a bit out, MuSeq was slightly ahead of the beat, so I fixed that and now it’s rock solid. Bad news is I discovered a bug in the MIDI library I was using, it doesn’t run on an interrupt, so any event that happens like say changing from the CVA page to the CVB page means that some MIDI clock ticks are missed, resulting in a massively out of time sequence, which is really annoying to say the least. I’ve had a look and it doesn’t look like it’s possible to modify the library to do this, so I’ll be writing my own library for handling MIDI using interrupts. Not a big problem, just a lot of code that will need stripping out and refactoring.
I’ve got a new module in the works. This is something I’ve had in breadboard for about 4 months, and I got the prototype PCBs early march (delayed due to COVID-19). You can hear a quick clip of the new module here;
The module is based on the somewhat infamous Korg NJM2069 VCF/VCA chip used in the Poly 800, DW6000/8000 and DSS1, here’s a picture;
This is only going to be available in the MU format because there are a plethora of really great VCFs for euro-rack, but only a limited range in MU format. Some of the nice things about this module is that it has a built in VCA, so for people with smaller rigs where space is an issue this module works really well as a “dual function” module. I’ve also added a switch so you can select 24dB/Oct or 12dB/Oct cut off slopes. Of course, being designed for a poly synth means the resonance is CV controllable which is a real boon (one of my favourite tricks is to route VCF envelope to both cut off and resonance). Finally on the back there are jumpers which can be opened and a header cable can be added to bring out the extra two pre VCF inputs and VCAs. I may do an expansion module for this to bring those extras in.
Now the catch, I only managed to get 25 of these NOS (New Old Stock) from a retailer who sells NOS chips, I would love to get more and maybe if I can find some I will. However, this run (when I find my oven for baking PCBs) will be limited to 25 only. I’ve tested these chips and they all work perfectly. However, I will be publishing me schematics, gerbers and front panel design, so you can make your own if you’re lucky enough to find one of these incredible sounding chips.
For now, please, stay safe and look after yourself and your loved ones, humanity has had some major crises in it’s existence, we will get through this one too.
