Description

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.

What’s New

Version 1.31

Added double tapping on a part in song mode, so before it starts, makes it start on that part first. Useful if you want to test out single part looping itself and you dont have to wait for first part to finish.
Double tapping used to just force the next part after the first part was played.

Ambitious mess

Disclaimer: I’m on an iPad Pro, and I own this developer’s other apps, so I knew the UI can be a little challenging, but this one is more of a struggle.
* Main issue is the sound engine tends to lag behind the user input and control, leading to a frustrating play experience. A groovebox that’s hard to groove with.
* Feature request: Add ways to randomize the sound setting, ratios, and patterns will lead to more happy accidents and faster workflow.
* There only seems to be four selectable algorithms unless I’m missing something, which is little disappointing.
* The sample looper seems out of place and difficult to use.
Maybe with some updates, performance improvement, and polish this could be fun.

Developer Response ,

Hi thanks for feedback. Could you email any feature requests as I don’t always see all comments on reviews.
I’m already looking at a nice new extra feature right now. Always good to hear of feature requests though and will look at those.
Ps there are 5 algorithms. The fifth one allows each operator to be a carrier (4 separate audible oscillators) while two of these still get to modulated themselves . This is common to be included in most FM synthesisers

Non legible small font unnecessarily

On an iPhone the fonts are stupid small for no reason. It amazes me! It’s like they don’t even look at their own product. Why do you make it so hard to read?! Fair sound that can be very strange but with an old fashion late 1980s UI. Weird animal.
