    Hard to say without hearing/seeing what you mean, honestly. My personal guess is that someone opened the unit to "fix" something and either wasn't able to accomplish what they set out to do or made it worse. The wheels not working is likely a cable not being plugged in (properly) since there's a dedicated cable running to the wheel assembly.


    Does the warranty label indicate that the TI has been opened up?

    I'd open it up, take the keybed out, remove the PCB with the diodes so I can access the grey rubber pads on the other side. Then carefully take them off and clean the contact surfaces with soapy water and rinse with distilled water.


    Are the 2 keys next to each other?

    No, it reduces the load by a tiny amount actually.

    250V is rather unlikely. What voltage did it have? 5V?


    > It was working fine which is why I never noticed


    If it was indeed 5V then I'm not surprised it worked.


    > and then I realised a strange noise coming from my synth


    Probably the inductors from the internal switching power supply operating at a different frequency than normal, nothing I'd lose sleep over. Do describe the sound you heard, though.


    > Got a light shock off the synth


    That's because of the unearthed power supply you were using, that's unfortunately normal and nothing to be concerned about. The voltage can reach 100V but can only supply extremely low current through high impedance which is why no damage is done.


    > I have left the usual supply at a studio so I can't plug it back in to test if its survived.


    That's okay, the TI2 will be just fine and if it has indeed been working with the 5V supply then I see no harm continuing to use it this way. Depends on the "strange sound", though.


    > Does anyone know if this will have ruined my synth??


    Again, depends on the sound. I see no reason why anything would break, however, so I'm optimistic that it's fine.

    This bug bit me today, so I'd just like to leave this here and make people aware that it's still an issue with 5.1.7.


    Symptom: Using sequencer mode, assigning a part to one of the analog outputs 1 to 3 has no effect and the part is still sounding on output 1.


    Workaround: Switch to single mode and back to sequencer mode. The analog output assignment is now in effect.


    This is especially annoying when the Virus starts up in sequencer mode since it means you'll have to apply the workaround every time you turn it on.

    > Die Demosounds sind alle sehr überfrachtet bzw Technomäßig. Das war bei dem Virus Rack damals nicht so.


    Die Presets vom Rack entsprechen nach meinen Kenntnissen denen vom Virus B - diese Presets sind auch beim Snow da, nur sind sie anders sortiert.


    > Ich hatte damals auch eine Soundbank mit einem OS Update bekommen, glaube ich.


    Ja, es gibt für die älteren OS-Versionen eine zusätzliche SysEx-Datei, bei denen der Demosong deaktiviert wird und der Speicherplatz statt dessen für weitere Presetbänke genutzt wird. Diese Presets sind nach meinem Kenntnisstand beim Snow ebenfalls bereits mit dabei.

    Maybe you can route the patch to Output 2 or Output 3 and feed it back using the input on the Virus? That way, you could have one patch for the dry synth and use another part that processes the input just for the FX and outputs it on Output 2 or 3.

    To be honest, I don't really understand the question. The Virus is a stereo synth, why would one want to record it in mono?


    Sure, if you disable the stereo effects and pan everything to the middle, the left and right channels will carry the same signal. That's placing an artifical crutch on the synth though. I'd always run it in stereo and mix it that way.

    You already solved the illegal RAM issue by replacing the battery. If it still shows, the battery that you put in is discharged as well.


    The "on some sounds, there is a lot of harsh crackling and it has frozen with a screeching sound once" issue is separate. I suggest you check if the capacitor that will eventually wear out has already been replaced or not, see https://64.media.tumblr.com/c6…p8i3gqpKF71sy7a0i_500.jpg for a picture and https://joeyfehrenbach.tumblr.…he-synth-repair-adventure for the full story of that person's journey.


    If it's brown, it likely hasn't been replaced yet and may be at the edge of failing. Either way, in my personal experience, if the capacitor is replaced and the DSP still crashes (= screeching sound or no sound), the DSP needs replacement.


    The crackling appears to happen when the linear 5V regulator overheats. If you open a side panel and let a fan blow into it, the crackling should be gone if that's the cause. For a more permanent solution in this case, use a 9V external power supply instead of the original 12V one. It makes zero difference for the Virus but lets it run cooler.

    The original DSP worked for some time but eventually, the sound issues re-appeared and the keyboard would stop working as well. Only a DSP replacement was able to fix it in the long run, unfortunately. Now it runs like new. Quite the strange affair, the whole thing, but since their power supply is so strangely designed, I'm left to assume that the DSP failure has to do with that. It's either that or the DSP itself failing after some time, which I would find rather hard to believe.
