Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Patterning & Dueling Ruismakers: A drum playground how-to
Using Patterning to drive two instances of Ruismaker via AUM: A drum playground on the backbone of a volcano
This experiment began here when I asked for suggestions for a good step sequencer to control Ruismaker. @brambos suggested Patterning, and the door opened. Both apps play remarkably well together with AUM as a makeshift chaperone. So much so that I am putting together this summary from my original thread, along with some additional tips, should you guys and girls want to get into some extensive (chaotic / beautiful) drum experiments of your own.
Here’s what you’ll need
Apps: Ruismaker, Patterning and AUM, which you should already have!
People around you who will tolerate how loud your life is.
Extract the .zip file attached down below and choose “Copy to Patterning” from the extracted file (_Silent.onpd). This is a decoy drum kit made of silent samples to mitigate any CPU load from Patterning. We won’t be using Patterning as a sound source, so we don’t need it to load a bunch of samples. This kit was made and very generously uploaded by @wim
Open AUM and create 4 channels. Insert Patterning on one, TWO instances of Ruismaker on the next two and we’ll use the 4th channel as the mix bus (trust me—you’ll likely benefit from being able to turn the whole machine down with one slider)
You can mute or turn down Patterning if it makes you feel better, but there is no need really since it’s just spitting out MIDI data while it plays silence.
Send the two Ruismaker channels to Mix Bus A, and set channel four to receive from Mix Bus A.
Set each instance of Ruismaker to receive MIDI from "Patterning"
Optional: place an EQ and some compression + limiting on channel four to keep everybody in check.
And thanks to @wim everything inside of Patterning is already mapped to Ruismaker. Head over to AUM and tap play. You should be hearing both instances of Ruismaker playing. It's now in your hands to combine them and get them to work together.
Additional tips & things to try
It's tough to define reason with two separate instances of the same drum machine running at the same time off the same sequencer, so embrace the fact that you probably aren't going to get a specific beat neatly laid out. Instead, go wild and throw every effect processor app you've got on Ruismaker's channels.
Open each instance of Ruismaker and fly through the presets. Land on one, tweak it a bit, save a new preset then keep tapping "randomize" to find another path. Then feed them through more processing apps. Distort one instance to oblivion, smash the other with a heavy-handed compressor and then feed them both through more distortion and more compression. In the example audio file below I was getting some charismatic results by following this no rules approach. Albeit, I didn't do a good job with the recording (make sure to watch your levels going into the mixbus compressor). But still, I got results I never would have gotten from a more traditional path to beatmaking. Have fun!
