It's doing well.

Emulation update: Finally, after weeks of debugging and bug hunting, the JIT / dynamic recompiler is taking its first baby steps and generates valid audio

Well done!

has there any improvement on the CPU intensity?

Yep, the JIT engine works and is being optimized for performance right now. The current execution speed peaks a 102 MIPS (we need 136 MIPS for a Virus C in realtime). Numbers are promising, given that it only took a few hours to get there and there is lots of potential left.

That's fantastic!! hopefully it helps open the doorway for other synths with more chips down the line!

Hi numerouno,

from its early stages, it was clear this was a cycle-exact emulator.

Will the "performance optimizations" have effect on the accuracy side (introducing high-level approximations of the DSP instructions) or does DSP563XX - and the additional, device-specific emulated chips - mantain its original DSP instruction/cycle-accurate approach ?

Not all all, there are no accuracy changes or anything like that, it will always be a 1:1 emulation

Greetings, it’s been a very busy and eventful month for us.

We're glad to announce that we finally have a functional VST (internal at the moment for testing purposes) that can run the synths by themselves in real time.

Realtime VST demos (Virus C) running on an i7 4790k:

Underruns are caused by the CPU, although the emulator performance is being improved daily

Amazing!

Thank you very much! this is the most exciting synth development to happen for an extremely long time!!

Do you think it's feasible now to do synths with multiple chips now?

Not just yet, we have plenty of single DSP synths to get through first

right!! I meant, does it seem technically feasible? I remember it being a concern that multi-chip synths wouldn't be possible because of how CPU unfriendly they could be. Since the new emulator is much farther ahead and now works in real-time, I'm wondering if that's changed
