Convert messages at scheduler time to low priority

Description

The jit.qball object places all messages received at scheduler time in the low priority queue, even if overdrive is turned off.

Examples

Messages

bang

Any bang received at scheduler time will be placed in the low priority queue. When the low priority queue services this message, it will be sent out the left outlet. If the message received is being sent from the low priority queue it is immediately sent out the leftmost outlet.

If mode = usurp , and the low priority queue has not yet serviced the last received message, it will be replaced by the most recently received message.

If mode = defer , then the most recently received message will be placed in the low priority queue without affecting previously received messages.

int

Any number received at scheduler time will be placed in the low priority queue. When the low priority queue services this message, it will be sent out the left outlet. If the number received is being sent from the low priority queue it is immediately sent out the leftmost outlet.

If mode = usurp , and the low priority queue has not yet serviced the last received message, it will be replaced by the most recently received message.

If mode = defer , then the most recently received message will be placed in the low priority queue without affecting previously received messages.

float

Any number received at scheduler time will be placed in the low priority queue. When the low priority queue services this message, it will be sent out the left outlet. If the message received is being sent from the low priority queue it is immediately sent out the leftmost outlet.

If mode = usurp , and the low priority queue has not yet serviced the last received message, it will be replaced by the most recently received message.

If mode = defer , then the most recently received message will be placed in the low priority queue without affecting previously received messages.
