There are two possibilities: 1.) The digital one needs "simple" mathematics: You need the lowest common denominator of both clock rates as master-clock and have to divide this master clock down to the needed individuall values. Example: you want a 8 step versus 7 step sequence with tempo 120. The lowest common denominator of 7 and 8 is 56. So you need a clock which runs with 56 beats per bar. 2.) The "analogue" version uses a phase locked loop (PLL - yeah! again this funny module): One sequence is running clocked by any wished clock, the other sequence is clocked by the oscillator of the PLL. The PLL compares the reset signals of the sequencer counters; if there is a difference it speeds down or speeds up the frequency of the oscillator. Of course this will take some time, lets say 20 to 30 cycles. Kind regards, Florian PS: You see, why I'd like to have a PLL-Module ;-) -- Florian Anwander |ConSol* HP-Support Tel. +49.89.45841-133 |Consulting&Solutions Software GmbH Fax +49.89.45841-139 |Franziskanerstr. 38, D-81669 München email: florian.anwander@consol.de |http://www.consol.de
