• 16 Voices Drum Synthesizer and Stereo Sample Player • 2 oscillators (16 Waveforms) per voice with filters, Phase and Ring modulation • 1 sample player per voice with sample position, filters, phase and stereo control • Expressive instrument: velocity amount per Amp and Pitch modulation (MIDI CC) • Randomization engine (Drum Synthesizer, Sample Player, Envelopes) • Advanced Pitch and Amp envelopes with multi control points and delay • Envelope templates, modifiers and copy/paste • Mute/Choke groups: reduce overlapping and keep your drums tight • Drag and Drop File Support and multi sample loading • Mixer: 16 voices (Multi Output - If Supported By HOST) • Pad controller: voices triggered by Pad (MIDI OUT and Velocity Sensitive) • Includes classic drum machines built in presets for inspiration • Library explorer: drums organized by category • iOS AuV3 (iPad/iPhone) - Advanced Responsive Design, portrait and landscape views Everyone agrees that the drums are a very important key element of almost every genre out there, they are the foundation of a song. We are all fans of acoustic drums and drum machines, they each have different characters and strengths. FAC Drumkit combines both worlds, samples and synthesis, in order to provide new exciting and unique sounds. As a rule of thumb, the synthesizer section brings the body of the sound, and the sampler the unique character. Both parts are layered together and contain essential parameters to ensure they won't clash and will sit well together. On top of the samples and synthesizer section, FAC Drumkit brings unique Amp and Pitch envelopes with precise control points to modify the curve in a gentle or extreme way. The envelopes play a very important part in the signal path because, thanks to their flexibility, they allow designing very special transition. Indeed, the envelope of a Clap is probably the best one to illustrate the benefit of such envelopes created with points. The burst kind of sound is very hard to replicate with classic ADSR, it's not the case in FAC Drumkit. Needless to say, thanks to the control points the pitch transitions are also more interesting and precise. The value of each control point can also be altered manually, to set the root note of a kick for example. FAC Drumkit is for everyone, as sound designer you will be able to synthesize your own drums in a fun and creative way. On the other hand, if you are looking for instant results, use the provided presets or load your favourite sample pack in the sample section of the 16 voices. The randomization engine makes the creation of new sounds really easy. Define what you want to randomize and you are ready to go. Remember that instrument category plays a role in the randomization process. For example, if you want to design a drum kick set the instrument label to BD (or use the voice index to get a wider sound palette). It's also very interesting to select a sound you like and start the randomization process from there, in a gentle way or not, thanks to the options available in the voice button (page selector). FAC Drumkit is an expressive instrument, the amount of velocity can be set individually for each amplitude envelope, and the pitch envelopes can be modulated by external MIDI control change messages. The pitch modulation applies on control points or on the whole pitch envelopes. Important: The standalone app is a factory version only and you won't be able to save user presets. Use the AuV3.

Progressions is an AUv3 MIDI plugin for your favourite DAW. It can be used to generate a unique set of chords that are unrelated to traditional scales, which become predictable and repetative over time. Instead, Progressions uses a unique way of mathermaically generating a series of related chords using only a root note and mode (major or minor). Chord sequences are limited by the selected complexity and freedom levels, which mimic the way traditional composers of old would wander away from tonality and back again. The complexity level start off at Basic, which uses only the most common chords (I, IV, V and relative minor ii, iii, and vi triads). As you progress through the levels, you can add parallel majors and minors, sus and dom chords etc. At level 3 we start to introduce 6th and 7th chords, and then 9ths chords, all the way to 11ths, 13ths, Quartals and all their variations. The freedom level allows us to specify how far to drift away from tonality (the root), even allowing you to create never ending randomized soundscapes. Progressions allows you to quickly randomize a toolbox of chords, that can be played in a variety of modes (block chords, arpeggiated, or strummed). These can be synced to a host application, triggered remotely or pieced together into a song. Song mode allow you to change play modes on the fly as well as being able to control many features of the app in real time. Progressions supports open and closed chords with selectable voicings. It has an intelligent algorithm that attempts to align top notes of chords, add additional bass, and open chord padding to give equal weight to chords with only 3 notes. You can even play with rootless voicings. The Humanize section allows you to control chord and note timings, as well as set velocity variations to ensure things don't get too robitic. Progressions also features an integrated arpeggiator and strummming pattern editor. You can load up to 6 arp and 6 strum patterns at the same time and seemlessly switch between them manually, remotely, or using song mode. If you run multiple instances, Progressions allows you to sync your chord pads, song chain, arpeggiator / strum patterns between instances. Progressions can be loaded as a MIDI plugin or as an Instrument for those programs that don't support MIDI plugins (such as GB). Additionally when loaded as an instrument, you can use either internal sounds (soundfonts) or send MIDI directly to other MIDI instruments. Features • Block Chord, Arpeggiator and Strummer modes. • Supports open and closed Chords. • Varying complexity levels of chords. • Freedom levels control how far from the root key you can go. • Rootless voicing mode. • Open chord padding support. • Additional bass note mode. • Supports all common chord types. • Edit the preferred chord list to exclude certain chord types. • Input MIDI control for chords and play modes. • Automatic top note alignment of chords. • Hold Pedal support. • Built in ARP and STRUM editor. • Humanize options for chord and note velocity and timings. • Comprehensive Song Mode with 256 steps and looping. • Randomize chord progressions, arps and strumming patterns. • Route Chord/Arp/Strum modes & MIDI thru to any of 4 output ports. • Supports soundfonts when loaded as an Instrument plugin. • Sync multiple instances of Progressions. • AUv3 compatible MIDI plugin supporting Sync to Host.

Verdict
The clearest difference is rating: FAC Drumkit at 4.7 against Progressions's 4.1. FAC Drumkit also leads on review sentiment (88% vs 67%). Progressions's advantage is in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 2 months). On ratings volume, ads, device support and iOS requirement there is nothing between them.
