Coarse Tuning
The coarse tuning parameter lets you change the pitch of the MC-303 in half-steps over a four-octave range. Since all registered parameter functions affect only the channel on which they are sent, you can transpose just the desired parts. This allows you to transpose a piece while leaving the drum and sound effect parts at their original pitch. Add the following messages to the event list of each track you wish to transpose:
Controller Value
CC101 00 Selects RPN function.
CC100 02 Selects coarse tuning as the parameter you want to adjust.
CC06 XX Sensitivity in half steps. The range is 40-88 with 64 being standard.

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.

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.
