r/AccessVirus

Good evening,

I'm seeking help with my Access Virus C. The story is long.

I stopped using it in 2016 (life....), and then turned it on again in 2025. Battery was dead (so banks A & B lost), no sound, slow transitions between patches. Power unstable.

I found a person in London that seemed to have a good track record of dealing with Access Virus synths. This is, in his words, what was done: "First I changed a few capacitors in the powersupply to enable it to start everytime. Otherwise it might corrupt the new firmware like it did the old one. Once I was satisfied it was starting properly I read the am09 chip which contains the firmware and compared it to the current firmware file I have. Unsurprisingly the beginning was scrambled so I “differenced” the beginning against the current firmware file and concatenated the difference. "

The synth played ok for a couple of weeks, and then started not turning on, until it was dead. The guy ghosted me. So I found another person, much more reliable. This is what he did: he changed all capacitors, new switch, etc.. Quite radical, as everything was gone south.

However, the person does not touch software, he only deals with hardware.

Now, power supply seemed fine. However, no sounds and slow transitions between patches. So I reinstalled the firmware again (version 6, via Bome SendSx). Nothing. After I have reinstalled it, now sometimes it turns on, but the display does not. I tried to reinstall it in chunks, then again as a single file, both parts. Again slow transitions, no sound. It does not receive data when I try to upload the original a & b banks. I'm not sure what to do. I spent quite a lot, but I really want to save it, because the sound is so cool. Maybe I should buy another one? Bu who knows in which conditions an access virus c might be these days...

any thoughts?

So I've had a Virus TI for a while and at some point I just got tired of not having a way to actually update its library of sounds. Alternatives for me at least didn't work. The official software hasn't been updated since before Catalina, and I needed something simple that I could use with my MacBook, a way to browse and organize patches and have some real-time parameter control for automation inside Logic without jumping through hoops.

I tried what was out there. Nothing quite worked for me so I built my own thing.

It's called Vyrux. It's a macOS app (AU plugin + standalone) that gives you:

- A patch librarian: browse, organize, transfer patches. Double click the patch to play it on the Virus

- Full SysEx parameter control in real time

- Works over standard MIDI

- MIDI channel selector, USB and DIN MIDI support (I highly recommend ESI MidiMate eX)

- Three UI themes (amber, red, white) to match your hardware

- Auto-updates via Sparkle

It works on macOS 11 and up, Apple Silicon and Intel. Virus TI, TI2, TI Snow, TI Polar.

On first install, macOS may block the installer, go to System Settings -> Privacy & Security and click "Open Anyway" next to Vyrux

There's a 2-hour free trial, no credit card needed. If you like it, it's €19.99 (ex-vat) one-time, no subscription. I made this solo and used it myself for a good chunk of time without issues.

Give it a spin!

Just picked up a TI2 and want to add the sound banks of the Virus into Logic so I can do midi program changes without having to manually search for the sounds in the Virus.

Anyone know of a sound list for the Virus? When I was researching OSTIris about a month ago, I came across a subreddit where someone credited someone else who had put together such a thing and now I can’t find the post. Thanks for any assistance.
