Heat Synthesizer Pro Customer Insights

1. I use it via a sound cable from my phone to record direct into my daw as a live instrument, I just love the sheer versatility of this synth... pro version is amazingly good value!!! (•‿•)Excellent sound and the VST works even on Linux (Carla host with Win VST bridge).

2. That will give it five stars for sure.I was under the impression that, with this app, you could load a VST file from your PC, and say, plug a USB to MIDI cable into any generic MIDI controller, and play the VST from your phone, with the MIDI controller.

3. Any updates coming?just writing a review as a reply to a bad review below... the description is very clear and has always been, I've had this app almost since it came out, it's always been known that this app does not load VST instuments, if you read the whole description it clearly states that there is a VST version for PC that you can load your patches in and use in your DAW.

4. Please note that the exported wav file is not being recognised by FL Studio, but the phone can play it.Fabulous app! The best I've found and there's hundreds of presets to easily download from the online community via the app.

5. "Still" because it has gone without love from its developer for some time and because the sound quality remains very good.It's a pretty versatile synth.

6. Vaguely worded, poorly written "VST Integration" page on the website only adds to the mystery and frustration.Really good sound, I use this for the live band pop song.

7. Great sounds with very low latency, I could seamlessly plug my midi keyboard and play like a real synthesiser, with chords.

8. There are a lot of great presets, including special ones like the laser saber of Star Wars that uses the phone's gyroscope.

9. Or at the very least, load a VST file onto my phone and play it in the app.

10. Awaited updateI love this synth and it's one of my workhorses but puh-leeze fix the time lag of the clock on the GBL.

11. Started to get a tad dated with other newcomers allowing deeper control but definitely in the top group for Android.Love this app.
