Interconversion between harmala HCl and freebase is easy. If you have one form you can make the other. To get freebase, dissolve the Ha.HCl in water and add base such as ammonia, sodium hydroxide or sodium carbonate.
To get Ha.HCl from freebase, dissolve it in 3% acetic acid solution and add hot ¾-saturated brine. Allow this to cool slowly, then refrigerate.
On The Wiki it is wrote:F - Redissolve harmalas in hot water, add sodium carb, filter (keep solids, discard liquid).
G- (optional) Instead of precipitating all the alkaloids in step F, first add sodium bicarbonate to precipitate harmine, then add sodium carbonate to precipitate harmaline
If you followed either of these steps at the end then what you have is freebase harmalas anyhow.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
