Disconest ~ Metadata For Your Music: Keys, BPM & More
Vinyl sounds better, looks better, feels better and even smells better. But digital does have its benefits, musical metadata is one of them. Having the key, tempo and other musical metadata for your records at a glance would be useful. Disconest uses The Echonest music database to find information about releases registered on Discogs.
As of November 2024 Spotify removed access to api endpoints used by Disconest and many other indie apps. Without these apis Disconests functionality is limited. See the Spotify Developer blog for more details.

ChordPro ~ Create Lead Sheets
In 1992 Martin Leclerc and Mario Dorion developed a simple text file format to write lead sheets, songs with lyrics and chords, and a tool to create neatly printed lead sheets out of these text files. The tool was called
www.chordpro.org/chordprochord, and the text files were calledchordfiles. It soon became a popular way to write lead sheets and many users and tools adopted this format for similar purposes. For still unknown reasons people started calling the fileschordprofiles.
The ChordPro (also known as Chord) is an ASCII text file format for transcribing songs with chords and lyrics. The format was originally used for guitar, but is used for variety of other string instruments, such as ukulele, bass guitar or mandolin. Although this format is legible as it is, there are many popular programs for displaying, transposing and printing. Files in this format often have extensions such as .crd, .chopro, .pro, .chordpro or .cho.

Blue Cat Chorus ~ Free Vintage Chorus
From a light ensemble to a deep destructive modulation effect, Blue Cat’s Chorus can just do anything, for free! The Chorus effect was originally designed to simulate several voices, just as if several persons were playing together the same notes, but with a variable delay between them. This is one of the typical effects that you can get with Blue Cat’s Chorus. But this plug-in also enables you to drastically change the original sound and create deep pitch modulation or crazy ‘bubbling’ effects. With the additional “Spread” control on the stereo version, the famous stereo widening and head spinning chorus effects are a few click away.
