FM TiNES is an electric piano library dedicated to the most beautiful FM electric pianos ever made. We know as musicians ourselves, that there is nothing more inspiring than the belly, crystal-like, tine sound of an FM electric piano. We ran through the entire 80’s gamut of the most beautifully expressive, rich, warm, and inspiring electric pianos ever made. The magic of our software is the expressiveness. We went to great lengths to make sure that all of our pianos are full of life, expression, warmth, and beauty, but providing an analog filter than can be controlled by velocity, and a color mod that will change the color and tone of the mod per velocity. When you combine both of these together, you create a very expressive electric piano sound that seems to change the tone on each and every keyboard touch. From beautiful tine stacks and layers, to wonderfully rich string and pad stacks, this will be your go-to library for all of your pretty electric piano needs.

A port of Dexed, a FM Synthesizer. Features over 20,000 Cartridges with 32 patches each. Comes with AudioUnit AUv3 plugin for use inside AUM and other DAW apps like GarageBand. Get a camera kit and plug in a midi controller through USB, or get a 5-PIN DIN 1/in 1/out, to: USB and use the camera kit through USB MIDI Spec, NOTE: some devices handle SysEx differently and therefore we cannot promise support for SysEx, so invest in connectors and cables wisely. If you have questions involving making MIDI-USB work the best for your situation, email support. This iOS app was designed especially with small interfaces in mind. Example: an iPhone 5S or a resizable window inside AUM. If one clicks the menu eye, a feature LOCK SCROLL can be –very– important to set knobs, sliders, et cetera: if screen size is limited. LOCK PARAMs in the eye menu locks the parameters for scrolling without knocking loose the preset. In the CARTs menu double tap a cartridge to load a series of patches, the files will have a .syx extension. To use MIDI CC, in the menu eye you must first turn on MIDI CC. When MIDI CC is on it makes the tap events react like a right mouse button click. NOTE: MIDI CC, in eye menu, doesn't have to be on after CC controls are mapped. MIDI CC touch modifier will also turn off after you have successfully mapped a CC control, or when you delete the current mappings. You can turn it on again later to turn off mappings or create new CC mappings. I would suggest setting CC knobs in the bottom section of the screen – above keyboard (if visible). Currently you must save patch in DAW – for instance: GarageBand or AUM. Once we can determine unity and saving/loading between the AUv3 plugin and the StandAlone app, external save will be eventually developed. There is a pathway set to transfer .syx files through iTunes to the StandAlone app, only. Other plans include fixing pixelated images, a quick zoom to set CC mode and updating GUI to a higher degree, make sure midi CC knobs update.
