S1 MIDI Trigger for iPad

There’s not a day that goes by that I don’t love my iPad.  I’m constantly finding new and cool things to do with it, and more and more I’m finding that it’s actually saving me money.

Another great example of this is the S1 MIDI Trigger app for the iPad.  It’s a MIDI controller app that works wirelessly with your DAW and allows you to play drum sounds, music notes, chords and MIDI CC controller data.  A comparable hardware device is the Korg padKONTROL costing $199.  The S1 MIDI Trigger is FREE or you can upgrade to the full version for $2.99.  The free version allows you to test the app, but is limited to two banks and doesn’t save.  The full version has the same engine as the free version, but allows you to save unlimted banks.

OK so how good does it work?  Well lets say I’m not going to ditch my padKONTROL just yet.  As of version  2.02 there is occasional latency, intermittent missed notes and notes triggered in succession are played up to quarter notes at 180 BPM (or eighth notes at 90 BPM).  Thus far I’m using it successfully to trigger drum parts and fills in Strike my virtual drum player.  I set the CC control sliders on the S1 MIDI Trigger to control the intensity and complexity knobs in Strike.  I also setup some cool chord banks to trigger chords in Omnisphere and that feature alone makes this very cool and fun to play.  I get a groove going and play chords or rhythms wireless from across the room… love it!

With a faster wireless home network you may experience less latency and intermittent notes.  I’m running a 802.11G network.  If you’re running a 802.11N network then your experience may be better.

In order to use wireless MIDI devices in your DAW you need a couple of downloads.  I’m running Windows 7 64bit so this should work if you’re using Vista or XP.

– Download and install DS MIDI WiFi “DSMI Server for Windows”.
– Download and install and a MIDI loopback driver. MIDI YOKE NT 1.75 There are others, but this works well for me.
– Run the DSMI server application and select “In From MIDI Yoke: 1” as Input…. “Out to MIDI Yoke: 1” as output.
– Minimize DS MIDI WiFi
– Start S1 MIDI Trigger on your iPad
– Open your DAW, selct a track and play

Here’s a demo of S1 MIDI Trigger:
