Vintage Synth Explorer

I have owned a Multitrak since 1985 and it has always been one of my favorites - alongside my SCI Pro One. One of the features that is rarely mentioned is the ability to do additive synthesis in addition to the more common subtractive. This is easily accomplished with its "Stack" feature, which is not simply a detuned "Unison" mode as is usually found on these older synths. Any or all of the six voices in the stack can be the same or different patches. Conceivably, you could create 6 wave patches representing the harmonics of a particular timbre and add them together. However, this leaves you in monophonic land as you truly only have 6 voices to play with. [cont.]

But you can create complex waveforms with 2 or 3 voices where each has its own envelope for the VCO, VCF, and VCA along with all the other parameters available. This will allow chord or duotone fingering. Stacking percussive bells can give excellent approximations of vibraphones or glockenspiels. Stacking different horn sounds gives a powerful brass ensemble. If only there were more voices available this would have had an unbeatable analog sound. The only other shortcoming I feel it has is the "softness" of the sound. Sometimes it seems like the MultiTrak is too mellow - but that's analog for you.

memory.So I;m going to replace the backup battery because it has
