What if your sequencer does not have two voltage rows, but does have a trigger output per stage (such as the RYO VC Sequencer with Trig Xpander)? Or if you have a sequential switch, instead of a voltage controlled one? In that case, you will need to use triggers set at specific stages to step between different clock divisions patched into the sequential switch: I demonstrate this in the last movie, below. For example, you use the /8 output to get quarter notes, then switch between the /4 and /2 outputs to get 8ths and 16ths. If you have or want to use a clock divider instead, you need a faster main clock – say, 32nd notes (8 PPQN) – and then divide that down to the timings you need. PLLs also tend to lag behind tempo changes on the incoming clock. The previous videos have used a clock multiplier, as I find it easier to wrap my head around “this is my core tempo the multiplications are the rolls at faster timing divisions.” However, multipliers tend to be more expensive, as they require a Phase Locked Loop ( PLL) to synthesize the higher clock rates from the main timing pulse. (It also adds an inverting attenuator to the division/multiplication VC input if you can’t get the above patch to work, make sure this attenuator is not set to 0.) Clock Dividers versus Multipliers The QCD Expander even gives you voltage control over the gate duration. This means you can set a longer gate time the “normal” notes, and shorter gate durations for the faster notes, which helps accentuate them by making them more staccato. Feel free to skip it if you’re busy and already know what ratcheting is:īy the way, if you happen to have a 4ms QCD plus its Expander, you can set different gate durations for the different clock multiplications. (There are far more details about the patch at the bottom of this article). If you’re not familiar with ratcheting, here’s a quick demo along with a brief explanation of the overall patch I’ll be using. I showed ratcheting using pitched notes, but it could also be used for triggering percussion modules. In the following movies I demonstrate three variations on this basic idea, showing alternatives in case the modules you own might have or lack some features such as voltage control of the clock division/multiplication. My favorite “generic” patch combines a sequencer with at least two rows – two voltage control rows, or one voltage control and one trigger row – with a clock multiplier or divider, and optionally a voltage controlled or sequential switch. Not surprisingly, there is more than one way to go about it. Originally attributed to Tangerine Dream (listen to their 1975 track Stratosfear – especially staring at the 3:00 mark – for a percussive example), ratcheting is appearing more often as a feature in sequencers and trigger controllers these days Doepfer has even released a “ratcheting controller” module.īut not everyone knows how to create a ratcheting patch on their modular. It does not store any personal data.Ratcheting is a Berlin School sequencing technique where an individual note in a sequence has its envelopes retriggered multiple times, usually at a musical subdivision of the sequence’s tempo – such as playing 1/32 notes in the middle of an 1/8 note sequence – to create a roll or what I sometimes (quite improperly) call a trill.
