DMT acetates ime are going to be a goo.
Idk about harmala acetates, i think they would be a solid though.
Two things to consider though-
1) why salt it, evaporate, and then add water again when converting your freebase into a tincture?
You can just take distilled water, weigh your freebase, and add enough acid to salt the alkaloids, but not too much. Personally i'd use a dry cyrstalline salt here, not vinegar. It will be more stable long term, taste less nasty, not be a goo if you ever want to evap a dose and put the powder in a cap, and if you sterilize everything, have far less of a chance of bacterial contamination over time.
IE-
Take 1g of your freebase alkaloids, find out the weight of the acid you are going to use, and figure out how much acid you need to salt the dmt/harmalas, so you don't use extra. With fumaric acid and dmt, its something like 25-30% fumaric acid by weight for dmt fumarate (1g of dmt fumarate would have ~750mg dmt, the rest is the fumaric acid). The percentage might be different for harmalas.
Then add your acid to a known amount of distilled water, lets say 750mg of dmt freebase, 7.5ml of water, and 275mg of fumaric acid. Then add your freebase dmt. IT should all dissolve, if not add a few more mgs of fumaric acid until it does. Then boil it in the microwave, in the dropper you plan on storing it in. That way its sterile, and chances are you wont get any contamination.
Do the same for the harmala tincture.
2) its going to be extremely bitter, theres not much that can mask the taste, keep that in mind when thinking you can make it palletable in a tea. Brews have more tannins, and other nasty stuff that makes you nauesaous, but tinctures are not to great tasting or easy to keep down either. I just disssolve my dry salts in water and take shots, chased with fruit juice when i do pharma. Its still pretty naueasous, and with caapi i actually perfer the tea. Mimosa tea i'll pass on though, dmt fumarate in water is much much easier to get down.
Really though, i'd store your alkaloids dry. They won't degrade as fast as in a water solution. Just convert your freebase dmt and harmaloids to a dry salt (citrate, maleate, fumarate are the only dmt salts that stay dry ime). Just look into salting by figuring out the amount of acid you need to freebase, and dissolve them in distilled water and evaporate. No need for fasa, you can get pure salts with a bit of math to know exactly how much acid you need to fully salt the alkaloids, without any excess. With fumaric its ~27%of the weight of your freebase.
Acetates usually are hydroscobic, and will be a goo. Tinctures are prone to contamination, and degradation of the alkaloids in them. Really, i think you should just salt your freebase dmt and harmalas with citric acid or fumaric acid, and get a dry powder to store it as.
Then dissolve that in water to dose when its time. Vinegar (acetates) don't dry very easy, and will pull moisture out of the air in the case of dmt.
Once your tincture gets contaminated, its done. You cant freebase it and recover the alkaloids safely, since the microorganisms may have created toxic compounds that get carried over in an acid base. Belive me, i've had caapi tinctures turn, and it sucks throwing away multiple doses of tincture because of bacterial growth.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.โ - Wendell Berry
