Welcome to 7XFM - a 4 operator FM synthesizer and 7 track sequencer with Ableton link, recording, and routing for your audio to connect to AUM or Audiobus. With most of the important synthesizer settings found in most FM synthesizers and added modulation. Modulate the operators over time with the LFO, plus dynamics for amplitude and pitch of modulators wherever you add an ACCENT Pick from a range of preset frequencies for carrier and modulators (influenced by Orla DSE/Bohm FM Expander synthesisers) Create those classic FM sounds from punchy Lately Bass to smooth 80s fm pads or crazy chaotic FM sound effects. Keep in Sync with your apps using Ableton Link or MIDI Send MIDI clock or MIDI note as separate channels. This app was influenced by the Korg Volca/Electribe FM synth sequencers as well as TX81z and Orla DSE9 FM synthesizer SEQUENCER The sequencer has 7 channels containing a sequence dedicated to a tone sound. You can create sequences using step edit or bring up the PIANO ROLL for quick step placement. You can just randomly generate steps - either random choice pitches or SELECT NOTES. or shuffle the sequence PIANO ROLL! its easy to create melodies and bass lines fast! Double click step to cycle though octaves or erase across step with finger motion. Mask keys so you can define keys and swipe across bar with finger motion to lay down steps easily. EFFECTS! Each track has echo, reverb and a low pass filter similar to add some spacial atmosphere or emulate an analogue synthesizer. COOL CREATIVE FEATURES! 2nd and 3rd voice generators with detune and transpose by semitomes for fat chorus effects or chorded notes Auto level ducking switchable input from bass metronome or any track Playback timing of notes on sequences - steps triggered either at 4th or 8th timings - a sequence can play slower and last longer equivalent to 512 steps Added a “mutate tone” option that slowly modifies the sound randomly away from original. Added “randomise tone” that completely creates a random tone from fresh. GLOBAL TRANSPOSE! All channels can be transposed simultaneously on the fly to create great layered melodies, and you can choose which ones are ignored (TR LOCK) for things like sound effects. SONG MODE is like a playlist of programs, where you can chain programs from either the current loaded program or imported saved program file. A scene can have any track muted, global transposed, reset counter at start (D.C.) "Da Capo", override step length and control the BEAT ON metronome mode. You can then arm sampling and record the chained programs and export the audio. Save your Songs and they won't be affected by changes in the original programs. EXPORT! You can easily record a perfect loop of whatever is playing and export via AudioCopy or Audioshare as well as email and IOS Folder Export your tones, sequences or whole programs to another device, friend or saved elsewhere SYNC This is compatible with Ableton Link as well as MIDI so you have options for connecting to external hardware or other apps while keeping in time AUDIO ROUTING Output the main audio to other apps such as Audiobus or AUM to allow those apps to record or process your creations EXTERNAL CONTROL Control Mute of tracks with midi keys, volume of track-channel with MIDI CC 176 for channel 1, , 177 - channel 2 etc .. MIDI note input of one track's sound available while sequencer is playing all tracks - selectable tracks controlled by all midi channels (omni) THIS DOESNT ACCEPT MULTIPLE MIDI PER SEQUENCE.

Fingerophone

Read full description

Fingerophone brings the feel of a classic pocket electronic instrument to your iPhone and iPad: slide a finger to play, with no extra hardware to buy. Slide across the compact hex keyboard to play an electronic tone instantly. It is a real monophonic touch synthesizer that makes its own warm, analog-style sound: two slightly detuned oscillators give it a vintage warmth, a resonant low-pass filter rounds off the digital edge, and vibrato adds the familiar wobble. Every control stays within reach while the note is still playing: - Four waveforms (sine, triangle, saw, square), crossfaded as you switch - Vibrato for the classic pocket-synth wobble - Tone to darken or brighten the sound - Drive to push it from clean into gritty - Volume A live oscilloscope draws the actual signal coming out of the synth, so the screen moves with the sound instead of running a canned animation. Scroll the keyboard across several octaves and play quick melodies, sustained drones, and noisy little riffs. Plug in a MIDI keyboard to play the synth, then map its knobs to the controls with MIDI Learn. The sound is generated on your device. You can play without an account or an internet connection. Whether you want to experiment with a pocket synth, explore warm analog-style sounds, or try a finger-played instrument without buying hardware, Fingerophone keeps everything on one focused screen.
