is a tempo synced/clocked slew limiter possible?

I’m trying to create tempo-synced automation in a patch. So far I’ve got this set of modules;

The polyphonic output of the digital programmer is sent to the glissando module to create a smooth transition between presets, then split and used to control various parameters in the patch. My question is; how would I make the transition last an amount of time determined by the tempo of the clock generator, rather than an absolute amount of time?

For tempo synced modulations you could check out MindMeld ShapeMaster Pro. You can create stepped patterns like that and it has built in slew.

You can also do all sorts of other stuff including drawing in your own shapes in fine detail. There’s a free version that includes everything except the clock syncing and a couple of additional expander modules so you can try it out first. The Pro version is normally $30 but down to $20 in the current Black Friday sale.

The CV outputs of each channel are mono, not poly, but it has 8 channels all of which can be synced to the main clock.

Manual is here:


Ah I looked at the free version of this last night while I was working on it! This may work for me depending on how slow I can make the envelopes.

If I’m reading correctly, because the slew amount is a percentage control rather than an absolute amount of time, the actual slew time will be dependant on the length of the envelope, thus achieving a smooth transition between settings that’s tempo synced?

The slowest (longest) synced length is 128 bars. But… you can kinda hack it to be longer by feeding it a slower clock. By default it expects a 48ppqn clock but can also be set to expect 96 or 192ppqn. If you keep it set on 48ppqn but send it a 24ppqn clock for example, then each of the synced lengths will be effectively doubled - 1 bar becomes 2 bars, 128 bars becomes 256 bars etc. If you set it to 192ppqn but sent it a 48ppqn clock, each length would be quadrupled. And 192ppqn with a 24ppqn clock would make each length octupled up to a max of 1024 bars. In fact you could even try it with a 12ppqn source and 192ppqn setting to effectively get a synced length of 2048 bars! Can’t say I have ever tried that haha but should work in theory… you’d just have to remember that the 1 bar setting is actually 16 bars!

As I said this is a hack though and while you won’t ‘void your warranty’ doing this, we make no guarantees of accuracy when the source clock ppqn and SMs ppqn setting are different.

It’s been a couple of years since we worked on that but yes, I’m pretty sure the slew amount is relative to cycle length.
