Insane Polyphonic Analog Synth Sounds - Insanely Affordable!

Get to know them!

Heads up, analog synth fanatics: The Tetra is about to shake up your world. This way-cool, way-portable synthesizer from Dave Smith Instruments gives you that unmistakable 100% analog sound, with - get this - four voices. You've got individual outputs for each voice, for uber-flexibility. And if you want to go radical, you can use Tetra's "Combo Mode" to combine four programs into unison or poly "super patches." Cooler yet, you can even poly chain Tetras - or a Prophet '08 - to give yourself up to 16 voices of polyphony.

Tetra gives you the hook up with two oscillators per voice - sawtooth, triangle, saw/triangle, or square with variable pulse width. You've also got three envelope generators per voice and two sub-octave generators per voice, to reign in that sound you're looking for. All-in-all, the compact Tetra is your source for sweet, all-analog synthesized madness, and it's got USB for serious recording/performance workflow integration. The awesomeness becomes clearer when you consider it this way: with this little guy, you've got four of Dave Smith Instruments' wicked little Mophos built into one...at seriously thumbs-up value. Way to go, Dave Smith Instruments. Way to go, Tetra.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
