how do I AUTOTUNE a voice?
On the left side of the control panel above the Mod Wheel, find the MASTER section, with a Volume and a Tune knob. Press the AUTO TUNE button beneath these, which will bring up the Auto Tune display. Press AUTO TUNE again to start the tuning process.
On the display, you will see each individual oscillator, pulse width, and filter tuned in turn. This takes about three and a half minutes, during which you won’t be able to play the unit. (Later, you can save time by tuning only the oscillators if you wish, by pressing the button under OSCFRQ in the display.)
Once the unit is tuned, you’ll see a chart showing the results of the tune. A ” T “
under each voice number shows that the voice was properly tuned. There is one row
showing the VCA tune status and one row showing the Oscillator/Filter tune status
(more on this later). After the unit has warmed up some more, if you hear something
off-key, you may press AUTO TUNE again.
The A6 also automatically tunes unused voices in the background without
interrupting playing. This is called Background Tuning. In addition, the A6 monitors
the temperature of the analog hardware and adjusts tuning to compensate for
temperature changes. This is called Temperature Tuning.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. 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. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

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.
