The Korg MS-20 mini is an analog synth, the reincarnation of the classic MS-20. The iMS-20 is the iPad version of the same machine.
If you just try to use the same settings on both, the first thought will be “The iMS-20 simply can’t sound like the real thing”. But in fact, they have different behavior for the same settings on the filter and envelope modules. Don’t expect to make the same sounds using the same settings on both!
With some work and listening carefully you can make the iPad app to sound much closer than before.
Here is another example, now using the filter with resonance and a big release time.
