Hello,
Thanks for your post.
The SampleTank app has two modes. LIVE and SONG. The LIVE mode will use different MIDI Channels for each part (There are 8 parts that can have their own instruments loaded), the SONG mode will offer different instrument 'parts' but these will all react to the same MIDI Channel. Try using SONG mode to learn these MIDI parameters. This will help you identify if this is a MIDI Channel issue.
Another way to check this would be using MIDI Wrench or MIDI Monitor. These are free apps for iOS which will help you identify what MIDI devices and messages are being connected/sent to your iOS device. These apps would show the MIDI Channel being used for these messages as well.
Hope this helps!
