Solar/Mercury very low volume

I'm having trouble with Solar/Mercury volume of samples. When I just start playing, I could barely hear anything and the sound peaked around -50-40db. When I crack up the plugin volume to max (12db) and I hit the keyboard really hard, I can get around -21-18db, which is what I would expect.

I'm using the default presets. Previews are played at normal, expected volume.

Do I have anything misconfigured? Is it known issue?


  • I am having the same issue.

  • I can second that - at least in Cusabe on OSX Monterey.

  • I am also having the same 'Low Audio Levels' issue. I am running Ableton Live 11 Suite on PC. I have submitted a support ticket for the issue. I'm just glad that it's not just me.

  • I'm having the same problem too. I'm running it in Logic Pro x in a Mac with Mojave

  • I have to run all the way up on audio and then increase the gain for it on Cakewalk. Win 11prox64

  • The same thing is happening to me. I have to add an amp to get any sound.

  • I have found that changing the Velocity to 'Exponential Pos.' and raising the volume to 200% give me plenty of volume to work with. You will find Velocity under the three dots ( ... ) next to the cog, top right of the UI.

  • This issue still persists for me. It makes the lower velocities nearly unusable. Changig the velocity curve works - but this cannot be the final solution.

    Is anyone at spitfire aware of this issue?

  • I am having the same issue with volume which makes Mercury unpairable in an instrument layer in Bitwig... Any update in the making?

  • Same here. Love everything but this issue makes me use this synth less than I want.

    In addition to raising the Volume (see my post from October 14, 2022) I have found that adding Velocity compensation works well. In Logic Pro and Ableton Live 11 you will find it in Midi Effects and you can flavour to taste. I have found raising the Velocity compensation to 127 (ie. the highest possible) works best in most situations but experiment and see what you like.
