Sequencer Plus / Re: Voyetra Sequencer Plus GOLD v4.11 (Aug 1993) for DOS
« Last post by RandomTestSubject on January 12, 2026, 09:54:39 PM »I have SPG running in 86Box on my Mac Mini M4, and it does quite well. For the tightest MIDI timing, make sure to select the small CPU frame option introduced in 5.x. There is also a MIDI input bug at the moment that can crash the input (but not the VM) but I have made the dev aware of it and they indicated a fix will be coming in version 6. You can work around this in the meantime by just using a very fast emulated CPU, I think mine is 400-ish MHz. Once the bug is fixed you should be able to use an emulated 386 or 486 at typical speeds. Also, if your emulated machine uses acpi, avoid using irq2/9 for your emulated mpu-401. Any other irq should be fine though. Oh, and you'll probably want to set your keyboard to PC mode in MacOS just to make life a little easier since SPG is largely keyboard driven. Once you account for these details it actually works very smoothly. The jitter is within 1ms plus or minus of the timing of SPG on real hardware, and the real hardware is within 1ms plus or minus of perfect.
Also, the latest version of 86Box has its own VM Manager now. Not sure if it is as feature-filled as MacBox, but it it works well enough for me. Let me know if you have any questions where running SPG in 86Box is concerned, happy to share what I know.
