Unparalleled SysEx Management for MIDI Hardware... Midi Quest supports 900 of the most popular MIDI instruments and other devices from over 50 different manufacturers including Korg, Roland, Yamaha, Kurzweil, Alesis, Waldorf, Kawai, Akai, and E-mu.. Store, organize, and edit banks and the individual patches, combinations, multis, performances, drums settings, and other SysEx loaded from your MIDI hardware. Midi Quest is a true multi-instrument editor/librarian designed from the ground up to effectively support multiple MIDI ports, multiple manufacturers, and multiple MIDI devices. Midi Quest "talks" to each MIDI device individually so it can simultaneously send SysEx to as many as 250 different instruments and still edit another instrument - all at the same time. Try doing that with any other editor/librarian... Midi Quest is not a panel editor. Midi Quest is a professional, integrated system capable of fully managing, editing, and organizing the simplest to the most complex workstation class MIDI devices and hardware synthesizers such as Korg's flagship workstation, the Kronos. Midi Quest natively reads and writes industry standard .syx and .mid files so that you can easily take advantage of SysEx downloaded from the internet or received from a friend. Midi Quest for iPad imports Set, Collection, individual Patch, and individual Bank files from Mac and Windows versions of Midi Quest so existing SysEx can easily be stored and edited on an iPad. Midi Quest can store an entire studio configuration - in a single file. First, what every editor/librarian should have (but may not)... Midi Quest will easily handle all of your bank editing tasks. Copy and Paste, Swap, or Insert single or multiple patches within the same bank or with other banks using menu commands or drag and drop. Along with a dozen other standard commands to rename, sort, shift patches, and so on. 1-tap audition automatically sends selected patches. Midi Quest's unique and powerful bank editing capabilities are highlighted in multi-timbral instruments with parent/child linked editing and display. Just like its bank editors, Midi Quest's parameter editors cover all of the basics with the features you expect - multiple ways to edit each parameter: grab and drag editing, extended popup editing, and true rotary knob editing. Unlike most panel editors, Midi Quest can retrieve and display all of the current values of all parameters. Of course, Midi Quest performs edits in real time so the instrument immediately reflects the changes made on screen. It also offers a range of both manual and automatic auditioning options. Scale each editor to a customizable size (up to 3X) so editing is fast and easy. Along with the editor's many features, take advantage of the Block Copy/Swap options which allows for the selection of a logical group of parameters such as an envelope, oscillator, effect, or LFO and copy/swap them within the same patch, or a different patch. Midi Quest is not just for the patch tweaker. Midi Quest has many users who have never created a new patch by editing individual parameters. Their secret is Midi Quest's five different patch generators: Mix, Blend, Mix All, Morph, and Gen 4. Each takes existing sounds and combines them in different ways to create entire banks of new sounds in a matter of seconds. This type of experimentation, without Midi Quest, would require days but with Midi Quest there are results in seconds. Looking for new inspiration? Looking for a sound but no time for programming? Midi Quest has the answer for you. Sound Quest's latest patch collection contains over 180,000 unique patches and is now accessible to everyone with Midi Quest using the unique Patch Zone view. This context sensitive view tracks the instrument and type of SysEx and automatically lists the available patches.

KeyStage is a master controller, AUv3 host, and audio mixer app designed mainly for keyboard players. With KeyStage, you can simultaneously control any number of hardware and software instruments using any number of MIDI controllers in an organized way. Each project consists of sections (which corresponds to sections of a song). In each section you can change sounds and sound parameters of connected instruments, create complex splits and layers of your keyboard(s), change the functionalities of sliders/knobs/pedals of your MIDI controllers by creating advanced MIDI mappings, write your own scripts, view PDF and JPG files (e.g. sheet music) and lyrics, and much more. LIST OF FEATURES • Connect any number of MIDI controller to any number of MIDI instruments by creating tracks. • Load AUv3 instruments, effects, and MIDI Processors. • Assign any region of your keyboard(s) to any connected instrument. • Change velocity curve and velocity limits, and create velocity splits and layers. • Transpose notes and restrict notes to any key using pitch shifter. • Create mixer units to combine audio signals, turning KeyStage into an audio mixer. • With the player units, you can play wav, mp3, and m4a files, add marker points, automate actions (like play, stop, move to a marker etc.) using custom translators, or trigger certain events (like changing sections) when the player reaches a certain marker. • Input units allows you to use the microphone input, or the hardware inputs of a connected audio interface. • The Main Mixer view allows you to control volume levels and pans of all tracks, connect effect units, and connect units to mixer units. • Create instrument presets to easily change sounds of instruments by choosing patch names from patch lists. • KeyStage can also import Cubase Patch Scripts to automatically create instrument presets for your MIDI instruments. • KeyStage automatically detects new MIDI connections and recommends matching instrument presets from a database. • Simulate auto-sustain on any connected instrument. • KeyStage has a multi-track recorder, which lets you record any number of tracks simultaneously. • Change or filter any MIDI signal using custom translators. Use “Relative Control” switch to smoothly change the parameters of your instruments without any jumps. • Use XY control unit to send control change and pitch bend messages to any connected MIDI instrument. • Create setlists, quick access all the songs in a setlist from a setlist bar, move to previous/next songs from live console or using external MIDI. • Create virtual MIDI inputs/outputs for KeyStage. • Use virtual MIDI piano controller to play connected instruments. • View PDF and JPG files. Link any page or region of any file to any section. • Backup and restore your songs and global properties to Dropbox. • Map special actions (like changing octaves, switching sections, changing pages of a PDF file) to notes and controllers using custom translators. • You can write your own scripts in custom translators, which opens up endless possibilities. • Use MPE routing to control any MIDI instrument using MPE controllers like Seaboard. Use custom translators to change the functionalities of each MPE dimension. • KeyStage supports smooth transitions between sections. Pressed notes will continue to sound when you switch sections. You can access demo videos and video tutorials on my Youtube channel.
