About CMP Grand Piano
The second best sounding piano app in the App Store (after "Colossus Piano")! Convince yourself by watching and listening to the demo video on our product website!
This app supports Bluetooth LE MIDI, as well as Audio Unit and Inter-App Audio!
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 In comparison to "Colossus Piano" this app especially has a lower resource consumption and runs thus also on much older devices.
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 several hundred voices.²
- Configurable audio latency down to 1ms.
- 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.
- Provides Audio Unit v3 plugin version of this app, which allows it to be used as virtual instrument directly within third-party multi-track DAW apps (iOS 9.3 and higher).
- Supports Apple's "Inter-App Audio" system for audio & MIDI streaming between other apps.
- 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.
- Export and share your song as MIDI file or as audio (.wav, .m4a) file.
- Unlimited amount of tracks.
- Unlimited recording and playback length.
- Open MIDI (.mid) files directly from other apps (i.e. from Safari, Mail).
- 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.
