## What is MKSensation Xtreme?

The MKSensation Xtreme builds on our renowned MKSensation plugin, delivering the most accurate sampled representation of the classic MKS-20 piano module. Rooted in gospel music, the MKS-20 has been a staple in countless gospel albums, often stacked alongside JV-Series, Motifs, and other vintage racks for a rich, dynamic sound. Traditionally, musicians relied on complex MIDI setups to blend and control layers in real-time. MKSensation Xtreme replaces decades of hardware, offering the same powerful layering and live performance flexibility in a single app.

With the power of modern iPads and M1 chips, MKSensation Xtreme provides the equivalent of eight Pure Synth Platinums. Each of the eight sound slots features independent AMP, Filter, Control, LFO, and effects, plus 8-insert effect slots (with up to five effects per slot), along with Global and Master effects. All effect buses are easily controlled via red faders, and, as with all our apps, full MIDI learn functionality is included.

Designed for live performance, the app not only delivers our signature sounds but also allows you to host your own AUv3 instruments and effects. You can seamlessly integrate external sounds, run them through our filters, AMP, LFO, and modulation, and enjoy the ultimate flexibility—whether using MKSensation Xtreme’s sounds or purely its powerful hosting capabilities.

iPad Version vs Desktop

The iPad version is identical to the desktop version as far as features, synthesis, and functionality. The only difference is in sound: We removed the second version of the MKS sounds, so that there is only one main version of the MKS soundest, instead of two different versions on the desktop. The quality is the same.

### 3/5 — Latence

*2026-07-11*

Depuis la dernière mise à jour, il y’a une très forte latence sur mon iPhone 15 Pro max. Je l’utilise avec une interface midi et un clavier maître.

### 5/5 — EP muito bom!!

*2026-03-08*

Recomendo, uso no iPhone 15, sem travamento.. roda perfeitamente

### 3/5 — Good app but could be more

*2026-02-13*

I love to use this app. I use it every Sunday for church and other events. I find that the sounds available does not vibe well with more contemporary settings. If there was a selection of felt pianos, shimmers effects, arps, plucks, risers, and etc; this app will have a better review from me. 

Also, the interface with the additional sound packs (Micro Piano, Clarity Piano, etc) is confusing. If it is all in one place along the other patches, it would be better.

Others things, I hope would be in an update is an button to be able to latch/hold patches and embedded pad drones within the app. All in all, the app needs be updated to accommodate contemporary settings as well.

### 3/5 — download issue, pls do attend to my concern

*2025-07-08, version 2.2.2*

I have paid the app for iPad, I also paid clarity grand but the how come I cannot download the sounds, the percentage download indicator remains zero no matter how good my network is..I am using iPad 6th gen on 17.7.5 iOS version w 86 go avail memory..pls help

Se escuchan bien mal Cuando de tocan en Vive

### 5/5 — Gente!!! Cada vez mais maravilhoso esse app muito mais que um app!

*2025-04-17*

Gente!!! Cada vez mais maravilhoso esse app muito mais que um app!

### 5/5 — Great app and Support Team

*2025-03-15*

This program is like the Roland RD-1000 and P-330 on steroids. I had a playback issue on my I-Pad after the last OS update. A few patches played but most were met with a thud sound or a high pitched squeal. Normal re-sets and deletions…didn’t work so after just a couple of days the support staff (who kept in constant contact) re-worked the app and now everything is back to normal. The reason why I mention this as I had an issue with another vendor (piano program) and it took them 11 months to fix the problem. Top notch support and many other excellent apps.

### 5/5 — Super Apps très pratique et simple d utilisation

*2025-02-26*

Je cherchais une application simple pratiquer rapide, MKSensation Xtreme réponds à toutes mes attentes la qualité du son est plus que suffisant et les réglages sont très simple d’accès même en LIVE. Midi en Bluetooth est un plus. Je veux qu’on vivre cette application.

### 3/5 — Clarity Grand Download issues
