This app supports "Audiobus" (requires iOS 7), Apple's "Inter-App Audio" System (requires iOS 7) and the "JACK Audio Connection Kit" (up to iOS 6.1.3) for audio & MIDI connections from/to other audio apps!

CMP Grand Piano is a high quality virtual piano sound module for your iPad, iPhone and iPod Touch. It is designed for professional usage on stage by connecting an external MIDI keyboard to the iPad / iPhone / iPod touch by using the Apple USB camera adapter or another adapter supported by Apple.¹

CMP Grand Piano provides a very realistic sound by using a very large collection of audio samples of more than 1.7 GB (uncompressed) in size. Various articulations of each key of a real piano were sampled in full length and high quality to assemble this realistic sound. Real-time disk streaming is utilized to playback the respective audio samples with very low latency.

Sound Features:
- Two high quality base sounds ("Grand Piano" and "Jazz Piano") with more than 1.7 GB in size.
- Two additional sounds available as in-app purchase ("Concert Grand" and "Upright Pianino") with additional 1.6 GB and 1.1 GB respectively in size.
- Polyphony up to 140 stereo voices.²
- Configurable audio latency down to 5ms.
- Integrated effects with 17 presets.
- MIDI velocity response curve editor to fine tune the feeling of your MIDI keyboard, save them as presets if you use more than one keyboard.
- App can keep running in the background, so you can play piano while e.g. using Safari or another app to display scores or surfing the Internet.
- Hermode Tuning: Makes the sound more brilliant by controlling the pitch of the notes in multivoiced music to better frequency ratios than with fixed tuning. This dynamic tuning imitates the tuning behavior of well educated musicians with string and wind instruments and of singers in professional choirs.
- Audiobus support (iOS 7).
- Supports Apple's "Inter-App Audio" system for audio & MIDI streaming between other apps (iOS 7).
- Supports "JACK Audio Connection Kit" for audio & MIDI streaming between other apps (up to iOS 6.1.3).

MIDI Player / Recorder:
- Record, save and load your songs in standard MIDI file format.
- Unlimited amount of tracks.
- Unlimited recording and playback length.
- Open MIDI (.mid) files directly from other apps (i.e. from Safari, Mail).
- Download or upload MIDI files with iTunes.
- Load your favorite songs as MIDI files from the Internet, and watch at the virtual keyboard how to play it.
- Metronome.
- Use the "Tempo Zoom" dial knob to i.e. slow down playback at any time and learn your favorite songs more easily.

Did it again!
Biznatchio

To save you some cash. Buy the red grand piano, the white upright in colossus, and the white grand piano in cmp. The white upright piano in colossus is the most real piano I’ve ever played. They’re breathtaking. Amazing tools. For 15 bucks ? A steal I’d recommend an iPad that has some Space.


Really the next best
John Hurt's Ghost

Piano app that is. The more expensive one from the same developer is the best and it has other functional advantages. This one is perfectly stable whereas the other can crash on my likely under powered iPad. It is rare that the other will crash, but this one is completely stable. I own many piano apps, but these two and the Ravenscroft are the only ones I use. This is the bang for the buck without question. I still prefer the Colossal Piano, but I could completely live with this one if it was all I could or wanted to afford. I particularly like the Bechstein on here.


Key spread please

Using a midi is great but sometimes not practical on the go. Key spread please and I will continue to throw money at you.


Did it again!

I finally caved and just bought the whole package. This piano is breathtaking. I have the red grand and white upright from colussus piano. and iGrand as well. All great tools. I didn’t think it could get more real than the white upright in colussus. For 15 bucks ? I’d recommend an iPad that has some Space.


The Thoroughbred of the lot!
Musecrafter1

I have bought every piano app available for iPad including iGrand ($19.99) and Module with the Ivory IAP ($70.00) and nothing sounds or plays like CMP Grand! This is simply the best piano app period! It's also the least expensive. The only negative is the cartoon looking interface but that has zero effect on the sound.


iPad's best
Canoesailor

I have them all. CMP has limited tweakability but the sound quality is my go to solo piano. Second is igrand also very good more adjustments and different pianos but lack realism depth that CMP somehow delivers. Korg module and Ivory, a slow 3rd. Both Ivory and Natural Grand sound electronic to my ears, not worth the half price deal nor the precious 3 1/2 Gb and I wish I could sell them back.


I've owned the best... This is as good.
Beckofballs

Let's see, I've owned Synth Ivory II American D and the Ivory Steinway, Alicia's Keys, Piano in Blue, and even the $600 VI Labs VST, as well as many other of those huge sampled libraries. I also have the iOS version of iGrand... So how good is CMP? The Grand piano is ok, a little thin.. But the Jazz Grand... Wow! What a beautiful piano. This is a piano worthy of one of those above mentioned VST sampled libraries. Is it better? Man I cannot say it's better, but just as good I think. In fact, combined with the iPad or iPhone, you have a compact grand piano that sounds superb. Is CMP better than iGrand? Yes most definitely.. iGrand is still ok, but there seems to be so much more "meat" in CMP. iGrand has a different tone.. And it's nice for something different.


Volume Button

It needs a volume control within the audio unit...


I Like It

just amazing!


Best sounding CoreMIDI app in the app store
BEMess

I've tried most of the CoreMIDI piano apps in the app store and this one is by far the best I've found. The sampling is wonderful and the control over the tone/reverb/response is awesome once you get the hang of it. It booted right up and immediately worked with my external controller, which hasn't been the case with all of the other apps. Very happy.
