Active Sensing

By Sweetwater on July 22, 1999

A constant MIDI message sent by some MIDI devices to confirm that they are still there and haven’t gone off line. It carries no other information and hasn’t been widely implemented in the industry. It comes from the early days of MIDI when some companies thought that if MIDI was interrupted it would be a good idea for instruments to change all notes to an off state. When implemented, a MIDI device will usually wait about 300ms for the active sensing signal to confirm MIDI information is still being sent. If it is not received within this time limit, all notes are shut off and the operation is returned to normal.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%.

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.
