About Crystalline - Shimmer Echo FX
Crystalline is a shimmer reverb/delay effect for Audiobus and Inter-app audio. Create synth-like tones and textures from almost any sound source, perfect for guitar, vocals, synths, sound design and more.
Crystalline is capable of a wide range of sounds, including classic "shimmer" effects from the 80's, unique pitch shifted delays and lush reverbs. Crystalline is a highly creative and unique effects processor.
Guitarists can plug their instrument into an audio interface such as the Apogee Jam and get the elusive shimmer reverb tone they've been searching for.
Crystalline supports Core MIDI via the Camera Connection kit, USB MIDI interfaces, Virtual MIDI and WiFi connections. The MIDI Learn function lets you easily assign your MIDI controller's knobs and sliders to control Crystalline's effect parameters.
Here's what users are saying:
"Wow Holy Cow! Guitarism 12- string into Crystalline and I thought it sounded like 'Under the Milky Way Tonight'. I can't think of an instrument that would not sound fantastic with Crystalline. IGrand, Galileo, Sunrizer(holy another cow!), IPolySix all sounded like awesomeness." - NoiseHorse (Audiobus forum)
"Crystalline isn't what I was looking for many years... IT'S MUCH MORE!!! I just can't stop using it!!! By far, the best effect for guitar I've used in my life!!! Thanks again!!!" - Leonardo Leite De Castro (user)

Crystalline features two distinct modes:
PERFORM and TWEAK.
• PERFORM mode is focused around four XY touch pads. Touch to control DELAY TIME, FEEDBACK, REVERB and LOW PASS independently for left and right channels.
• TWEAK mode features large expressive sliders and additional effect parameters, allowing you to fine tune your sound.
In addition to Audiobus and Inter-app Audio support, Crystalline can also process external instruments such as guitar, voice and synths by connecting a microphone or professional audio interface such as the Apogee Jam, ONE, or any iOS compatible USB audio interface. Guitarists can use our effects live by connecting the output of their audio interface to an amp.
