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 Cinematic Machine Aparillo is an advanced 16 voice FM synth tailored for complex sound structures , majestic motions, moving and evolving soundscapes and atmospheres that are perfect for film, TV or games. It‘s not limited to the conventional fm sounds but also delivers a huge range of styles from basses to brasses, pads to leads to even percussion. ••• SYNTH ••• It is based on two interacting FM Synthesizers capable of forming the most complex timbres. A clever arrangement of synthesis, wave shaping, filtering, FX and modulation unfolds into a serious sound design tool for epic sonic creation. Aparillo uses many parameters that can be modulated for individual adjustments PER voice. Each of the sixteen voices interact with almost two dozen targets in a variety of ways for a continuous transformation and to create endless rhythms and melodic progressions. ••• FX ••• The integrated effects include a free-signalflow Filter/Spacial Comb device, a polyphonic Auto Pan with multiple waveforms, the obligatory Delay, our finest Reverb algorithm, and a Sugar Bytes innovation, the Spacializer. This is a very special breed of delay based effect, which can work as a delay, reverb or tuned comb filter and can add room, plucked strings or even pinged percussion to your sound. ••• ORBITER ••• The superstar of Aparillo is the Orbiter, an instinctual "mass-controller" you move through Aparillo's endless sonic universes for one-touch sound morphing. That finally gives you unlimited control over new grounds of sound manipulation. Aparillo for iPad will seamlessly integrate with your mobile studio setup. We built in MIDI support (Virtual, Network, External, Bluetooth), Audio Unit v3 and Ableton Link. Syncing your presets to use them accross other devices couldn't be easier with iCloud.

Verdict
The clearest difference is review sentiment: Aparillo at 89% against MidiQuesti's 10%. Aparillo also leads on rating (4.9 vs 1.5) and ratings volume (506 vs 11). MidiQuesti's advantage is update cadence (weekly vs every 4 months) and iOS requirement (10.3 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.
