Mixing and Scratching

So now that we know how to mix, scratch and effect sounds on the fly, let's take a quick look at advanced settings, and then we'll talk about how to record your mixes.

This is the configuration control panel. You can change the audio device that tX uses to send its audio output if you want to use something other than the default /dev/dsp. You can also change the size of the audio buffers, so if you have a very high-performance system you could turn down tX's buffers to get extremely low-latency playback. You can also change how often the graphics update so for the same high-performance system you could set the graphics to update often (for the tightest live control).

Now that we know how to control tX, we want to record something. There are two ways to record our performance. We can hit "Record" and then "Play" to record a set, but that only records one session playing between soundfiles that are pre-loaded into tX. Which has a lot of fun potential in and of itself, as you can record all your LADSPA control movements and also the firing of samples via the "trigger" button. What you can't do as of yet is automate the loading and unloading of audio files with the sequencer, so to make a DJ "mix tape" you need to record the audio output of tX to another program.

In order to externally record, you need to either have a full-duplex soundcard and use a commandline program like ALSA's arecord, or you can record onto another machine (I record to a desktop with an Audiophile 2496 soundcard running Audacity under Redhat 7.3), or record to the external medium of your choice (cassette tape, minidisk, external CD or HD recorder).

It's also fun to use tX as a live performance tool. I've performed live at small venues in Los Angeles since '00, and used to use it on a measly 233 PII (with low-latency tuning). I have some recordings of my own with tX on my personal site, asapien.org.
