I have Virus C and MnM. They don’t have the same sound at all. So this would not be a problem to join Mono to Access.
But your second point change the discussion.
There is a lot of gear suggestion to do. It depend on what kind of toy you want ?
synth, drum machine, sequencer…
In view to stay with mono discussion, we can say that this “toys” will be very fun and can be a good companion for your virus.
There’s a forum member on here who goes by Acemonvw, and he has a VirusTI2, and TWO Monomachines! His music is awesome, and he’s a super nice dude too, so I bet if you sent him a message, he’d be happy to share his insights.
Another +1 for the VirusTI and Monomachine. They really do compliment each other beautifully. Sadly I haven’t been giving my TI much attention lately. My Monomachine and Machinedrum combo have been more than enough to keep me happy. But, it’s always there to thicken things up in a pinch.
