It’s EXACTLY what I’ve been craving on iOS. Thank you thank you thank you!!!!!!!!!" - cenz music "Best chip app. - Is a great sounding, great looking, and great quality app. Everything is intuitive. Congratulations!!!!!! I’ll be telling everyone so know about this." - Always Don't Mess With Me Moby Chip is a four track, easy to use, chiptune, music sequencer. It was designed to recreate that old-school 8-bit video game sound. Each track is monophonic and generates sound from user definable, 4-bit 32 sample wavetables, or random pitched noise for drums and sound effects. The wavetable oscillators are bandlimited, using a proprietary algorithm, calculated in real time, and modeled somewhat after the original GameBoy’s wavetable channel. Moby Chip was design with professionals in mind. It’s great for creating chiptune songs or sound effects. It has sample based timing with accurate tempos. Export options include full song or phrase with selectable tracks and four file formats: wav, AAC/m4a, caf, ringtone/m4r. Exported audio files are ready to use without editing. Drop them into your favorite App such as Ableton Live, Apple Logic Pro X, or use them in a video game. These files can be accessed outside the Moby Chip App in the Apple Files App or accessed through iTunes File Sharing or in the Finder (MacOS 10.15 and newer). Moby Chip can be played live. Plunk out a tune on the onscreen keyboard with accompanying music provided by the Notes Grid (main screen) or the Song Editor. And like the music trackers of old, each note of each track can be individually edited. The instrument, octave, volume, glide (portamento), pan (including old-school delay stereo effect), arpeggiated chords, and trill effects, can all be adjusted per note. And one of my favorites, the Notes Grid supports triplets. You can find in-depth information in the included manual. But don’t let that keep you from jumping in and trying it out. Also, eight song examples are included in the app to learn from. Have a whale of a time!

GSi Free Vibes. Physical modeling emulation of a Vibraphone. This istrument emulates the sound and the behavior of a Vibraphone. It doesn't make any use of sampled material as the sound you hear is completely generated in real time thanks to some pretty complex math calculations performed by your device while you play. Main Features: - Physical Modeling - no samples - Full polyphony (49 notes) - Two different modes: Keyboard or Mallet - Adjustable mallet hardness - Available as stand-alone and AUv3 plugin - Very low CPU and RAM usage Buying the PRO Version gives access to additional parameters: - Built-in Program manager with unlimited programs - Authentic Tremolo effect that does not kill the attack transients - Harmonic manipulation parameters to craft the sound in more detail - Decay parameters for both the short and long notes - Ambience and Microphone settings - Mute Below Velocity function to mute notes if the note-on messages is below a given velocity level - Extended integrated user manual PLEASE NOTE: the IAP is completely optional, the instrument has no limitations. USAGE The usage is pretty simple. The main interface shows the layout of a classic 3 octave Vibraphone, from F to F, but the sound engine can generate up to 4 octaves, from C (Midi note #48) to C (Midi note #96). Touch a bar to play it, the lower the touch goes, the higher the velocity is. Operate the sustain pedal by tapping the icon on the bottom right. Parameters are: - MODE: choose between Keyboard Mode or Mallet Mode. As opposed to Keyboard Mode, in Mallet Mode the sound will not sustain while the key is depressed. - MALLET HARDNESS: adjust the hardness of the mallet from soft to hard, this will affect the attack and the way the whole instrument reacts to velocity. The Settings page offers only two settings: - Tuning: default is A=440 Hz, but this can be changed from 430 to 450. - Midi Channel: default is OMNI, but you can set it to receive on a specific channel.
