SooperLooper Display on IPhone
I've been working on a new live setup which uses SooperLooper - the bad ass looping software for OS X and Linux.
I can operate the thing with my footboard, but I still get confused about loop position and which loop is selected. After a night of research and a night of programming I came up with a solution which would let me leave my laptop off to the side - safe - and still see the relevant information during performance. Here's a video of me recording some loops into sooperlooper with the monome and pages app - and then the pudding.
SooperLooper Displaying on IPhone with processing and TouchOSC from sam_square on Vimeo. I've used Processing and the oscP5 library to 'intercept' OSC messages, do some computations and send them off to the IPhone (running TouchOSC) over a network. It shows loop position of the four loops and which loop is currently selected for modifications. I do have a few years of programming knowledge, and learned java in school, so I cut and pasted examples form the P5 docs. Most errors were due to data type errors and capitalization(float is not Float, even though it lights up?). Here are the basic steps: Register processing with SL to get updates on loop length, loop position and the selected loop Listen for incoming messages and store the loop length in a variable. It only comes in once in a while. The loop position is constantly coming in. These measurements are coming in a floating point number which equates to seconds. Take these two values and calculate the loop position between 0 and 1. If a 4 second loop is at second 1 in the loop - I need to send .25 to the fader in TouchOSC on my IPhone. Update the toggle buttons in TouchOSC if I get a new value. I probably do this inefficiently by shutting them all off and then turning the active button on. I've attached my script file - it will get you started. You'll need to substitute your SooperLooper Port number and your IPhone IP or network name. You can set the network name by naming it in iTunes and then adding .local to it - ie my phone is flyawayphone.local. It is lacking a few features - it doesn't grab loops until they are actually recorded. That means preexisting loops don't animate. Also you need to have your max # of loops setup on start of the processing script. This could be fixed registering an add loop event. I'll add these features in soon.
|Free EXS24 and samples - Circuit Bending a Casio||
NOTE: Use batteries when doing this - touching the power supplies while plugged into a wall socket can lead to health issues or death!Here is a instrument I made by taking apart an old casio keyboard and tying a copper wire between two tiny screwdrivers and touching solder points that were never meant to be connected. If you've never done this and you have an old keyboard around, give it a try. I've mapped the low bass sound to outputs 3-4 and the tapping sounds at the top of the keyboard to 5-6. Below is an example of this instrument in use. Some effects and liberal use of the cutoff filter on the ESX24. You can import these samples into your preferred sampler as well - they are .aif format.
|Max for Live Abstractions||
Max is a visual environment for making your own MIDI, audio and video contraptions. I've been learning how to use it since I got my early present last week - Max for Ableton Live.
|Free EXS24 Drumkit and Samples||
This is my Sonor Force 3001 sampled and painstakingly placed into EXS24. There at least 4 velocity levels for each sound. Many more for the snare and kick. Thousands have gone before you - download it with assurance you will have tasty drums coming forth from your amplified speaker system.
|Free EXS24 Beat Box Kit||
Free beat box EXS24 kit for your enjoyment. Samples are dry, recorded with Sennheiser e602. Preview MP3 track is attached.
|Ableton Live Drum Pack||
I've converted my EXS24 Sonor drum kit into an Ableton Live Instrument rack which uses the Sampler instrument. You'll need to own that plugin. There are several chains holding samplers. After you've installed and opened the pack, click the downward pointing arrow next to "SamsSonor" on the SamsSonor track. You'll see the subgroups where you can mix and add effects. Enjoy! Update: I've also added the simpler version.
