MidiStick V2.0: Next gen tesla coil interrupter

[TMaxElectronics]

Hypervoice is a feature that I added to the Midistick quite a while ago. It adds a second pulse with adjustable phase to each note. So for example at a phase of 90° you would get a second pulse after one quarter of the period of the note expired. That effect adds much more depth to the sound, and also allows for more expressiveness. Especially when you add modulation to that phase in VMS it starts sounding really good

The current Firmware has the feature sort of hidden away a bit, because I wasn't 100% confident in it when I released it. It is however used in some of the example vms maps and you can enable it for sid playback (there the phase is adjusted based on the pulse width register) by enabling the experimental features in the show mode window:


Keep in mind that for some songs that will reduce the audio quality instead of increasing it. When a high note is playing using the effect the overall volume drops down pretty far and you don't really hear the other tracks too much anymore. That is mitigated by the volume scaling feature in the new software I'm working on, but for the moment you can't really do much other than disabling hypervoice again.

...designing a little case to go around the stick.

I was working on something similar while I wait for my stick to arrive, can't wait!

Do you have a CAD file for this?

I can't seem to get hyper voice to work. I enable like you've shown, but nothing changes,
and after closing show mode and reopening it, the "show experimental features" box is un-selected again.
Any ideas what's going on?

[TMaxElectronics]

The box unselecting itself is intentional,. But what exactly do you mean with "nothing changes"? The effect depends on the SID you are trying to play, some don't actually use the effect at all. It could also depend on the settings you have selected for your coil (ontime, dutycycle etc.). The setting also doesn't exist in midi mode, as hypervoice is controlled by VMS there.

Ok, I see. I was trying to use it for midi mode.
Some sort of tutorial on how to create VMS maps would be really nice, unless you're planning to change how it works with the new version.

Yaay project update time again (finally)

I've had the beta version of the midibox hardware here for almost half a year now but just didn't get around to working on the software a lot until recently. I'm still in the "get the new software to work as well as the old one" phase of the project, but that has come a whole lot closer to completetion. I currently only implemented midi mode, but the others are soon to come aswell.

Right now I'm considering if I should do a small beta hardware production run and distribute that to people who want to test the new version and give me feedback on the changes I made, but that needs at least one more hardware revision.

Here's a picture of the hardware (with the IF-E96 transmitter in this case, but HFBR is of course also still supported ):


The use of a USB-C port actually had a funny side effect... you can now very easily use your phone/tablet as the signal source There are some pretty cool midi apps (at least for android) that I would love to try on a coil.

One of the major improvements that I did with the new software is to move away from a one timer per voice setup. In the midistick every voice is running on its own Timer to generate the pulses, which takes up all of the hardware i have available, leaving nothing for other ideas.
But the new software only needs two for each output, pre-calculates the delay from one pulse to the next in software and then writes that delay into the timer after the current pulse was triggered. I initially only planned to use this to free up hardware timers, but am now considering moving to more voices too.
I've been running all my tests with a voice count of 6 and am pretty happy, although it does sound a bit too chaotic at times. Especially since Hypervoice turns that into effectively 12 Voices if active on every channel

More updates are sure to come soon(ish )

Hey Thorben, any News about the MidiBox ? Can we already build and test one ourselves or is it still in closed development?

greetings and thanks,
