Virtual ANS is a software simulator of the unique Russian synthesizer ANS - photoelectronic musical instrument created by Evgeny Murzin from 1938 to 1958. The ANS made it possible to draw music in the form of a spectrogram (sonogram), without live instruments and performers. It was used by Stanislav Kreichi, Alfred Schnittke, Edward Artemiev and other Soviet composers in their experimental works. You can also hear the sound of the ANS in Andrei Tarkovsky's movies Solaris, The Mirror, Stalker. The simulator extends the capabilities of the original instrument. Now it's a full-featured graphics editor where you can convert sound into an image, load and play pictures, draw microtonal/spectral music and create some unusual deep atmospheric sounds. This app is for everyone who loves experiments and is looking for something new. Key features: * unlimited number of pure tone generators; * powerful sonogram editor - you can draw the spectrum and play it at the same time; * any sound (from a WAV file or a Microphone/Line-in) can be converted to image (sonogram) and vice versa; * support for MIDI devices; * polyphonic synth mode with MIDI mapping; * supported file formats: WAV (only uncompressed PCM), PNG, JPEG, GIF; * Audio Unit Extension (AUv3), Audiobus; * many new features compared to version 2.3; see the full list: https://warmplace.ru/soft/ans/changelog.txt Homepage, user manual and versions for other systems: https://warmplace.ru/soft/ans

Got GAS? Hi, I'm Nico. I play guitar, so I buy guitars... and amps... and pedals... and for years, I've been looking for an app like this. So I finally decided to make one. With GASlist, you can log every guitar, bass, amp, pedal, synth, or drum kit you own — with photos, detailed specs tailored to each type of gear (all the geeky stuff that actually matters to us, this is honestly what took me the most time but I think it was worth it), the serial number, and your estimated value. This is the Gear section. What makes GASlist different — and IMO makes it the best app to track your gear (but I'm obviously not objective) — is the Rigs section. Build a rig for each of your musical projects and always know what gear you're using and who you're using it with. You can also keep all your project info in one place: upcoming shows and rehearsals, locations, setlists, band riders, and more. At any time, you can export a clean PDF catalog for each item or your entire collection. Flex on your bandmates, properly insure your rig (because yes, there's a specific place in each entry to store the purchase invoice), or just send it to that person who asked for more info because you just put a piece of gear up for sale. WHAT'S INSIDE Log guitars, basses, and a genuinely absurd list of stringed instruments — 9-string electrics, baritones, microtonal double-neck guitar/basses, lap steels, electric sitars, you name it — as well as pedals, synths, and drums. Track everything you own with the specs that actually matter (the nerdy stuff, but we know it's actually important). Build rigs from your gear. Snap up to 3 photos per entry for free, or up to 10 with Premium — because one angle never does a two-tone sunburst finish justice. Choose between dark and light mode. Export a shareable PDF catalog or a full JSON backup. Works offline — your collection shows up even when the venue Wi-Fi doesn't. Sign in with Apple and sync across every device you own (we know it's more than one). GASLIST PREMIUM Unlimited instruments, amps, and pedals. Unlimited rigs. Up to 10 photos per entry. Search your entire stash. Basically: no more excuses, no more limits — just more GAS. PRIVACY No ads. No tracking. Your gear, your data, your business. Export or delete it whenever you want. I'm just a musician, so there's no shady stuff. Actually, it's made by a musician, for musicians.
