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.

SimplEQ Processor Plugin (AUv3) SimplEQ is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. To configure audio settings in standalone mode, tap the Settings button. Please note that the input will be muted by default to avoid nasty feedback! Overview SimplEQ is a very simple EQ - the clue is in the title! For those times when you don't need "surgical precision" and seemingly endless parameter options to tweak, SimplEQ might be just the thing for "broader brushstroke" EQ tweaks. SimplEQ is also very kind to your CPU. The frequency bands have been tuned so that they overlap and interact slightly, giving a surprisingly flexible range of tonal sculpting. Whether you're doing a quick rock mix master, or simply want to warm-up or add presence to a track, SimplEQ might get you there - fast and simple! For a super-simple lightweight "mastering suite" you could partner SimplEQ with the LevLr2 dynamics processor. Controls Active - Toggles the EQ On or Off. You can use this control to A/B your settings with the original signal and this will fade gradually between the two with no distracting pops or clicks! Each of the frequency bands can be cut or boosted by +/-6dB and because they overlap, they are very interactive, so use your ears, and dial-in to taste! Sub - Adjusts extremely low frequencies centred around 50Hz. Bass - Adjusts low frequencies centred around 100Hz. Lo Mid - Adjusts low midrange frequencies centred around 250Hz. Hi Mid - Adjusts high midrange frequencies centred around 1KHz. Treble - Adjusts high frequencies centred around 5KHz. Presence - Adjusts very high frequencies centred around 10KHz. Out - Applies a final stage gain trim to the output at the very end of the internal signal chain, between -24dB and +6dB.
