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.

The purchase button is unresponsive in either version so I cannot buy any module. ### 4/5 — Great tool *2024-09-15, version 1.3.0* Ir you have a Classic Synth, you must to have this great tool. ### 2/5 — Une appli malheureusement buggée *2024-04-15* Première impression excellente : la connexion avec un Pod Line6 v2 depuis une interface M-Audio fonctionne du premier coup, et l'édition des patches marche dans les deux sens. Malheureusement, la déception arrive après quelques dizaines de minutes lorsque l'appli demande que l'on achète une licence, que le bouton d'achat ne déclenche aucune transaction... et que l'édition du patche reste bloquée jusqu'à ce que l'on change de patch. Quel dommage. ### 1/5 — Roland xps-30 unsupported *2023-05-16, version 1.3.0* I would purchase if xps-30 was supported. ### 1/5 — Schade schade *2022-07-11* Ich würde wirklich gern meine Synthesizer mit dem iPad verwalten, aber bei 69,00€ pro Synth oder gar 249,-€ für das Gesamtpaket bleibe ich lieber bei meinen Alternativen. **Developer response:** Per synth prices aren't fixed at $69 but vary based on the complexity of the synth and can be as low as $29. Also, if price is a concern then Essentials is a less expensive option with fewer features but the same basic editing capabilities. ### 1/5 — $450! *2022-04-18* Jeez, crazy price. **Developer response:** Hello Clive, I'm not sure what currency we're discussing here but individual editors are as little is $29US with all 850 instrument modules at $249US. Anything more than that is likely taxes added by your government. We're certainly not seeing any of it. The Essentials version of Midi Quest is less at $199. ### 2/5 — MX49 Needs Studio View Arrow, Tetra needs a Keyboard *2020-08-09, version 1.1.3* I purchased the DSI Tetra editor. The programmer is similar to the discontinued Sound Tower Mopho iOS editor. You can easily edit programs, combis and sequences using an iPad. Please add a Midi keyboard screen so I can edit and test sounds using only the iPad and Tetra. Other functions are good. I tested the MX49 performance editor. This a port of the VYCRO MX editor. This lets you change the Midi channel, velocity and key range of parts 1-16 so you can make complex layers and splits. The MX module has a Midi Keyboard but the keys are too small to play. The MX module fills the entire screen and does not display a "Studio View" arrow. When restarting the app it defaults to MX editor. I cannot select any menu items, buy the module or switch modules unless I delete and re-download the app -- then I lose my Tetra and MX patches... Please fix. A bit of programming will make this a nice iPad synth editor. ### 1/5 — Complete crap *2020-04-12* Starts with message „insufficient RAM“ on an iPadPro 12.9 2018. Prices for single modules are bad jokes. ### 2/5 — I wish this worked reliably but constantly freezes (among other concerns) *2020-02-20, version 1.1.3* This app could be a great, especially for those with vintage synths that need a robust librarian and editor. I own an Ensoniq SD-1, Casio CZ-1, Casio CZ-101, and Korg DW-8000. I purchased the $69 license for the Ensoniq SD-1 because this may be the only iOS apps that provides librarian, editor and Sysex support for this keyboard. Unfortunately after several hours of use, I’ve discovered what the app claims to do only work part of the time. It constantly freezes, then after force closing, settings and edits are lost. I’ve tried being patient, reading the help guide but there don’t appear to be any solutions. For the price of this license, the app should be rock solid and bullet proof. It’s not even close. Other app developers have found a way to create similar apps that are much more reliable and at a far more reasonable price. Please Sound Quest, put some development resources into updating this app, fix the bugs and reliability issues. If you don’t your essentially gouging and scamming users. ### 1/5 — Fonctionne pas *2019-07-13* Korg kronos 3.1 Sur iPad pro11 2018 écran noir avec mise en attente. Essaye pour d autres synthes pareil.. 😠 ## Frequently asked questions about MidiQuesti ### What does MidiQuesti do?
