Good question. This is why we came up with a newer method using the FX spacer. The whole point of the spacer is to delete the trigger (main input) channel. This prevents increases to the gain of the channels involved.
Great idea. Sounds like you're looking to vary the volume or pitch of a sound with an LFO, which would result in a tremolo or vibrato effect, respectively. It is fairly simple to use an LFO in any of the synthesizer instruments (and the DirectWave sample player) on FLM since they all contain a dedicated LFO tab (or LFO controls under another tab) for doing just that. Next time you're on FLM, try playing with the amount (strength of the LFO), speed (the rate of oscillations) and target (choose either pitch or volume) on an LFO tab/controller.
To produce a vibrato choose "frequency" (usually abbreviated FRQ) as the LFO destination. As for producing tremolo, choose "level" as the destination. Note that some synthesizers (for example, minisynth) don't have "level" as an option for the LFO destination. In this case you could try setting the destination to another parameter, such as the filter frequency (usually abbreviated FLT), and try to mimick a tremolo effect, the success of which will depend on the amount of LFO applied (the more the merrier) and whether the cutoff frequency set in the synthesizer's filter tab is near the base end of frequencies produced by the particular sound you're working with.
Thanks mate, great suggestion. As gain staging is rarely so cut and dry it may take some time before we release a thorough FL Studio Mobile tutorial on the topic. In the meantime, for some basic and useful tips on getting started, we suggest watching: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pinNLBnBRe8.html, while using FL Studio Mobile's very own FX Analyzer to monitor the loudness (e.g. in LUFS) of a given track.
Hey, we understand it is a longer process than that outlined in our earlier tutorials. However, it is totally worthwhile because the process outlined in this video gives you a legitimate, clean sidechain in which you no longer hear the signal used for ducking, the trigger. Please check the description of this video, where we included a .flm file with tracks already sidechained as in this tutorial.
