The Tidal boot-up procedure has changed, so with Tidal 1.0.0-pre installed, you'll probably get errors when you start your editor.

You can find the new startup code here: https://github.com/tidalcycles/Tidal/blob/master/BootTidal.hs

You can just run it in a tidal buffer and all should be fine.

Vim

If you are using vim-tidal, check out the instructions found on the README.md file. You need to use the 1.0.0-pre branch of the plugin.

Controlling latency

There are two configuration values which control overall latency, 'frame timespan' and 'latency'. To find the maximum total latency, add them together. Here's an example configuration:

tidal <- startTidal (superdirtTarget {oLatency = 0.02}) (defaultConfig {cFrameTimespan = 1/20})

Frame timespan

This is the duration of Tidal's calculation window in seconds. The default is 0.05 seconds, in other words a calculation rate of 20 frames per second.

If you find Tidal is using too much CPU, increasing the frame timespan will probably help.

Latency

If you get late messages in supercollider, you can increase the latency by increasing this from its default value (which at the time of writing is 0.02).

SuperDirt running in another host

If you're running SuperDirt in another host (perhaps, in a multi-user setup), you need to define this in a similar fashion as with the latency, except in this case the keyname is "oAddress":

tidal <- startTidal (superdirtTarget {oAddress = "192.168.0.23", oPort = 57120}) defaultConfig

In case you need to alter multiple settings for superdirtTarget, just separate them by a comma ({oAddress = "1.2.3.4", oLatency = 0.04}).

Note that in emacs (and possibly other editor) configuration files, you'll need to escape the quotation marks.
