Sampler Synthesizer

Features & Capabilities

THIS IS A DEPRECATED PRODUCT. Get KQ Sampei 26 instead.

If you bought this app recently, you can request a refund.

A sampler synthesizer which sound sets can be changed. It is multi-timbral. Available Sound Set Formats: Sound Font(sf2), Compressed Sound Font(sf3), Downloadable Sound(DLS)

Supports a part of common MIDI messages (GM, GS, XG, MPE). Includes a MIDI File Player. It supports Standard MIDI Files and RIFF MIDI Files. It also supports multiple ports and loops.

Supports external storages. DO NOT USE ON-DEMAND LOADING WITH SLOW STORAGES SUCH AS HDD, USB STICKS, SD CARDS.

You can customize sound sets with "Modifiers". In default, a modifier which adds soft pedal function, and GS Custom Controller mod are being applied. You can select "Original" and disable GS Custom Controller if you want. Supports Audio Unit v3 and Inter-App Audio. You can use this synth as a plugin for another app such as GarageBand, AUM, Cubasis, etc... To maximize compatibility with other SoundFont players such as FluidSynth, select the engine V3, turn off "Custom GS Controllers", "Slow LPF", "Smooth Volume Level".

Supports Micro-tuning. Place AnaMark TUN files into Tuning folder.

You can use sound sets as long as the device memory allows. The actual memory limit seems to be around the half of the hardware RAM. Not that the limit of Audio Unit is much smaller. You may be able to load sounds over the memory size if you turn on "Load On Demand" (Streaming load). In the developer's environment, 4.2 GB of SoundFont could be loaded on an iPhone with 1 GB of memory.

You can play this app with external MIDI devices and Virtual MIDI apps.

If you own the original KQ Sampei (now KQ Sampei Legacy) make sure to go to the bundle to upgrade for $2.00 rather than spending another $9.99 for KQ Sampei 26.

This app is amazing it has 128 keys and it can handle black midi’s! It is very cool.But the problem is It should have a record button and zoom in and out for the keys please add those features It will be very nice but this app it is worth buying it.

The Ryouta Kira MIDI music apps are great. We use them on our iPhones, iPads, and iPad Pros. We would also love to be able to buy them for our Apple-silicon Macs. The apps are highly recommended to music contacts and sound system integration clients. They have also enabled a variety of church music that was difficult to provide in the past with excessively complex music production software. For KQ Sampei app, we would like full persistence in settings between app uses. Currently, when the app is shut down or running in the background, the user interface shows that all settings for pan, expression, chorus, and V.Delay have been reset. Some day a merging of the music curation features of MIDIREC, and app keyboard that provides MIDI-Out from the app with the existing KQ Sampei would also be greatly appreciated.
