Sketch Synth FX

The App is described as awesome (4/4) by the iPad music apps magazine Apps4idevices, but if you are new to Sketch Synth then Sketch Synth 2 is the best reviewed so have a look there first. They have a review and video which act as a great starting point for letting you see how cool a product this is:

Best support is on devices with dual core CPUs: iPad 2, iPad 3 and iPhone 4S, on older devices it is restricted and not as good. Testing could also not be done on older iPod models so this app is only recommended for iPhone 5/5S/4S, iPad 2 or newer.

Sketch Synth FX lets you draw effects onto your sounds, layer by layer using it's XY pads. Simply work from the sample input at the left, through the effects channels and to the output at the right. You always work on samples/recordings, Sketch Synth FX messes around with your samples, what it is not is a guitar amp (although you can record your guitar with it, I recommend using a separate record with input level monitoring and then using Audio Copy and Paste to copy the sample across).

You can record and export using Audio Copy & Paste (Sonoma not intua yet) or iTunes File Sharing. The effects you can apply include: delay, distortion, low/high pass filter, pitch, chorus. The effects can come on pretty strong and so you have a bypass control that really helps smooth chaotic effects into nicer evolving sounds.

This version comes with 3 themes / sample packs, including one sample pack from DJ Vadim.

Best support is on devices with dual core CPUs: iPad 2, iPad 3 and iPhone 4S. On older devices you will notice that measures have been taken to restrict recording length and lack of cpu can mean layering multiple effects together can cause audio clicks and crackles, also recording takes time to save as well. I wanted initially to take it off the app store for these single core devices; but it is not possible now it is up, so I will being working to bring a whole new load of low cpu effects instead.

Sketch Synth FX also comes with Sketch Synth 3D and Sketch Sound 3D now, so if you have one of those then make sure you get the latest updates and you'll get this automatically (albeit with fewer samples).
