I searched the forum, and I did not see any other posts about this.
It seems like the stretch algorithm could be improved or perhaps different algorithms for different types of material could be offered. In Ableton and Octatrack there are different algorithms for different types of material.
I am mainly asking about this in the context of pitch shifting samples by un-linking pitch and time, and then moving the pitch up or down. There are tons of artifacts, especially at higher pitches.
Side question: Anyone have any tips for getting the most out of the existing algorithm?
- If you MIDI sync to a DAW you will have jitter, which is not a huge problem (to me).
- If you MIDI sync with Ableton, then Ableton will not latency compensate your slaved machine. So, as the latency of your set increases, the more out of time your slaved machine will be. Try it! Add like ten compressors to a track with the lookahead set to 10ms in each one. Notice how bad your sync is. That is a huge deal (to me).
- The Deluge has a clock input. That means that you can sync with audio instead of MIDI. If you send the audio clock out of an Ableton External Audio Effect, it will be latency compensated and jitter-free. You can roll your own clock pulses with Abelton's Samper, or you can use a third-party plug-in. Expert Sleepers has one. Here's a free one: http://www.shaduzlabs.com/blog/24/a-free-plugin-for-all-your-clock-needs.html. All you need is a free output on a sound card to send the clock pulses.
The fact that the Deluge can be synced with an audio clock is HUGE. All modern rhythm machines SHOULD have that option.
Thanks for the reply. Yes - digital artifacts can be cool when you want them.
I found the Octatrack and of course Ableton do a decent enough job. Not expecting perfection.
One of my favorite things to do is slice melodies and then rearrange them and pitch shift some of the slices.
Maybe the option to choose a couple different algorithms would be cool. One for beats, one for melodies, and one for "complex" material. Something like that...
In my experience, most hardware machines I've dealt with have had more than satisfactory timing and very low levels of jitter. The only thing that bugs me (and I am picky) is the crap clocks that come out of DAWs. So, for me, I would not buy one of these devices if I were not syncing to a DAW.
ES uses their plugins for different purposes. You will not need most of the controls on the ES-4.
For some reason, the default settings on the ES-4 have it launch with MIDI/CV 1 = 1. That is what is causing that signal. Turn it to Off.
After the ES-4 plugin, add an Ableton External Audio Effect (EAE). The Audio To of the EAE should be the output you designated on your audio interface for sending the signal to the ES-40.
You might find this post helpful, which I made on the Elektron forum a while back. This stuff can be a bit fiddly, but you will get it sorted with some patience and manual reading.
