Another Combo V (Vox Continental) and Combo F (the Farfisa).
I've used them both loyally in Windows 8.1/Sonar Platinum X64 with no issues what so ever.
They are free and they are semi deep in editing ability's (Automation for Trem pedal, exc).
The Vox Continetal/Combo V is my favorite out of the bunch.
Yes you can buy them from autrua but the free ones are pretty decent.
The free ones don't have multi timbre samples (no velocity). So if you are editing them in the Piano roll view and drop
the velocity of some of the notes, they wont change, its all the same sample.
